Equations of Lines and Graphing

[@megansnyd74]

You are an excellent tutor!! Instead of hiring a tutor for my *Intermediate Algebra" class, I now just go to your KZbin channel, and watch your videos. Since I have been watching your videos, my Intermediate Algebra grade has gone from a D- to a B+. Thank you so much for putting your algebra videos here on KZbin.

[@sheet-son]

This guy performs truly an invaluable service, and for free!! thanks Prof Rob!

[@profrobbob]

Randy Savage THANK YOU for the awesome promo! It's always nice to hear when a student realizes all the effort that is put into educational channels like mine! Thanks again bat-cat:)

[@karenrei2278]

i wish you were my math teacher, you made all the calculation so easy to comprehend and thank you for all of your videos. God Bless You and again thank you (:

[@mellib2086]

I love that you are using a real chalkboard! Rockin it old school! Thanks!

[@profrobbob]

+MeLLi B you're welcome and thanks for choosing my channel to learn from!

[@profrobbob]

HAHA:) No problem. Thank you very much for watching. Sorry for making you try a post a comment three times! I am a full time teacher and my students know about my KZbin channel too...of course. Because of that, and I don't want any potential problems at work, I approve any comments before they are posted.

[@georgesadler7830]

Professor RobBob ,this is a clear and precise lecture/video on the Equations of Lines and Graphing. Students should be familiar with this material from Algebra I&II.

[@profrobbob]

I'm just happy that my videos are helping you so much to keep you watching and learning! Thanks for always taking the time to thank me but you really don't have to...it's thanks enough that you have chosen my channel to learn from!

[@annmcb]

I can't thank you enough for making these videos. I am over 60 years old and very grateful for all the extra help you are providing for my PreCalculus studies. It's like having a tutor at home every day. Another wonderful lesson. Thank again!

[@profrobbob]

You are so very welcome A Lauris and thanks for sharing your appreciation...are you working on a career change?! Teaching thru KZbin has brought a whole new dimension of teaching for me...almost daily my wife and I are amazed at the many different ways, places, people, ages and lives we are able to reach thru these lessons. THANK YOU again for being one of them...BAM!!! (not to mention that a tutor a day would be quite costly as well...but glad I can provide this help for FREE:)

[@annmcb]

ProfRobBob Mr. & Mrs. Tarrou, I am not making a career change, but I will be graduating this December with an AA/academic studies degree; this is my last subject. I am foreign born and we did not have colleges where I grew up; we do now. I know “we are never too old to learn” and it’s truly a blessing to live in this wonderful country; “the land of opportunities.” Also, Mr. Tarrou I feel like teaching math is your calling, because your teaching techniques help us understand the material. I spent hundreds of dollars on tutors in the past, but I'm grateful I found your channel. May you and Cheryl be blessed always!

[@profrobbob]

A Lauris We too are grateful you found this channel so helpful and we are glad you took the time to share your story and appreciation with us! Please know that in December when you receive your AA degree, that we are there in spirit, applauding you on your grand accomplishment. You're so right that "it's never too late to learn" and pursue your dreams:) Please let us know when you graduate...until then, thank you again for your support and all the kind words. Students like you are why I love to teach!!! ~ Best Regards, Rob & Cheryl

[@sukhjeetgrewal07]

I'm in my final year of Mechanical Engineering and I've just managed to understand equations of line.. now everything i studied in the past makes sense.. Thanks Professor

[@profrobbob]

You're welcome Sukhjeet! Glad I could help:) Some people dream of success…others wake up and work hard at it-Winston Churchill Keep up the hard work…it will all pay off!!

[@farida.azarleon9103]

Thank you for all this, now I understand graphics and they don't seem confusing. You're cool, man.

[@annmcb]

Just to let you know, I received my AA degree in December 2014, graduation ceremony will be this coming May. Thanks again for all your help.

[@profrobbob]

CONGRATULATIONS!!!!! A Lauris That's wonderful and we are very excited for you...it feels just like one of my own classroom students is graduating! What are your plans for the future now? Thanks for sharing the great news with us and we wish you happiness always:)

[@sincerelycayla4057]

Thank you so much for making these videos! Yours are one of the only videos that explain the math in a way that makes sense to me! Thank you!!

[@profrobbob]

+Sincerely, Cayla you're welcome and thanks for studying and subbing! Spread the word for me:D

[@profrobbob]

Yes...it is always a good idea to rewrite your slope as a fraction to you can see the rise/run vales when you graph:)

[@afaq96]

Hats off to you sir always optimistic and trying to give the Best. My university is going to start in august and thanks to your videos I'm gonna rock (BAM!!) calculus. You are the best .

Thx a lot Sir, the concepts on lines and slope are crystal clear.

[@peevestheprefect]

That's fine! I completely understand, and you're welcome!

[@DasianInvasian]

You sir are amazing. I was having such a hard time trying to understanding point slopes and different formulas. Not only did you explain it really well, you also gave out very useful examples with thoughtful explanations step by step. And because of that you just got yourself a sub. Keep up your outstanding work and I like how you have enthusiastic attitude towards your audience while you teach compare to other teachers who bores everyone. Again thank you so much for your great lesson you put up there :)

[@profrobbob]

[@suyy.288]

yeah , that's right . i'm always thinking , how if you are my math teacher. because my math teacher is teaching us so fast. and it's totally confusing. so what I do is . If i get home i search for our topic THAT YOU teach and watch it. and that's it ! my classmates always wondering how can I get high grades and HOW I can understand our teacher. i'll just say , ummm. let's just say , i have another math teacher that helps me a lot about our topic. THANKS A LOT FOR YOUR HELP :) not because of you I'm not able to win the elimination for the Math quiz bee :) thanks again, YOU ROCK \m/ ProfRobBob

[@profrobbob]

Lee Hiroshi_22 you too! Don't forget it helps this channel groW if you like, subscribe, support the ads, share with friends, classmates and teachers as an additional study reference so everyone can get high grades like you!...BAM!!!

Very well explanation

[@profrobbob]

THANKS!

[@slovan]

How do you do? Can I graph a line -2X+1, by changing it into -2/1x+1?

[@HERKFOOT21]

You really do make the best straight lines without a ruler! I'm going into pre cal and i just wanted to know what i'm going into. After just finishing trig the videos of this play list so far seem like a review of algebra 1 with the slope stuff and i kno i did good with that so that won't be hard to remember. Is trig going to come back into pre cal? will we be doing a lot of those trig proofs again? (which i know were your absolute favorite of all math! lol) thanks again i just wanna make sure i'm prepared!

[@profrobbob]

HERKFOOT21 So you took Alg 2 and took Trig as well? If Algebra 2 was honors level and you did very well and Trig was an an entire semester course PreCalc will be a lot of review of skills you already know but should go faster than you are used to. Trig will be in a few chapters of PreCalc and the last chapter covered should be introducing you to limits for Calculus.

[@richardgray8593]

Do you have somekinda stencil or other gadget to make that coordinate grid on your chalkboard? I first thought it was permanent until you erased it.

[@profrobbob]

Yes...it's a pull down grid screen that you chalk over...BAM!!!

[@profrobbob]

WOW...thanks for sharing that awesome news with that glowing testimonial! And thank you to for supporting by subscribing:) I hope you will continue to share your experience and my channel info with others who might benefit as you did:D (I apologize for taking so long to reply...you got lost on the list temporarily:(

[@horizonbrave1533]

BAM! (Sorry I had to add it in for you Proffessor RobBob! ) Anyway, so I'm not sure if this is even a valid question, but here goes. Atleast for linear graphs, it seems like all equations are solved for Y... We always either plug in numbers and always are interested in the Y value, or Y intercept. Why is this? Why can't we find the slope using X = my+b ? Or just solve for X instead of Y?

[@profrobbob]

Remember we have our independent or explanatory variable on the X axis and the dependent or response variable on the Y axis. Therefore it is natural to find slope as rise/run... or a better definition is the amount of change in y per one unit of change in x. This written definition is much better for word problems and interpreting what slope represents in a real world setting. X is explaining the change in y basically. Now this being said, when you get to Calculus and start finding slopes along a curved graph it can be easier to find the rate of change along the y axis instead of the normal x axis. The derivative (slope) of y=x^2 is described by dy/dx=2x... this is going to keep the x axis as the independent variable basically. If you have a parabola opening sideways with the equation x=y^2, the derivative (slope) can be found with the equation of dx/dy=2y. If you solved it for y, getting y equals plus or minus the square root of x. The derivative of this equation is more complicated to work with and not a good option. So you have a valid question, but finding slope with equations solved for x instead of y is something I doubt you will do until Calculus. BAM!!! haha This video is about integrals instead of integration, but it deals with the same idea kzbin.info/www/bejne/f2TFqaWfepiLmK8

[@randolflazaro9982]

THANK YOU AGAIN :) :)

[@profrobbob]

Flodnar Wehttam I wish all my students studied like you do!

[@profrobbob]

I have a career where I have homework every night like my students do!

[@euniceduong9079]

i'm not sure if this has to do with anything, but what if the equation is " y = x-3 " i have this maths test tmrw, and when i tried to do this in my book, the answer said something else...

[@sudhirkumarparashar2868]

Thanku sir ! It really helped. :) U certainly are doing a great job (y) :D BAM !!!!

[@profrobbob]

You're welcome...THANK YOU for choosing Tarrou's Chalk Talk to learn from!

[@kalathomas193]

Could you do a video where you have the slope but no b? ex. y=-1/4x

[@profrobbob]

For your equation the y intercept is 0 since there is no apparent constant b, and the slope is -1/4 or down 1 and right 4 from the y-intercept of 0.

[@coltonmccoy8194]

You should talk to Hank Green about making some Crash Course math series.

[@profrobbob]

I tried to reach out to them a couple years ago and did not get a reply...but it could be a great addition if I had any free time to make it happen. Thanks for watching...maybe you should suggest it and see if "you"get a reply...BAM!!!

[@coltonmccoy8194]

I sent them an email.

[@profrobbob]

BAM!!! We'll see...stranger things have happened:)

[@coltonmccoy8194]

Yup, stranger things have definitely happened. "Stanger Things" is an excellent netflix produced show btw, if you have time between youtube and teaching :) Think Freaks and Geeks meets X Files and The Goonies.

[@profrobbob]

sounds great...but it will probably be another 10 years till there is that kind of "free time" :)...NOT complaining though!!!

[@net5599]

Isn't standard form Ax+Bx=C instead of Ax+Bx=0 because the last one is in general form?

[@profrobbob]

+WhItE RaVeN Textbooks vary a little bit sometimes and this is one of those examples.
