08 - The Point Slope Equation of a Line, Part 1 (Writing Equations of Lines)

Get more lessons like this at www.MathTutorDVD.com.
In this lesson, you will learn how to write the equation of a line using the point slope form.
In this method, we must know the slope of the line along with any point on the line (not necessarily a y-intercept). We will solve many problems to get practice.

I'm so glad to see that someone out there understands that a lot of us need to WHY things are the way they are. A very good verbal and visual explanation is much appreciated. A whole lot of us would have done a lot better in math had we had a teacher like this guy. He's the absolute BEST!!!

[@jasonbelcher4476]

Exactly what I said in a different video. Simply astonishing how good he is at teaching math concepts.

[@BeautyGirlyStuff]

I use your video explanations all the time. You a very good teacher! Very concise which I appreciate.

[@freedomaugustus1555]

I just don't know what to say.. i've been looking on KZbin for a video that explains how the point slope form is derived but non of them were explaining this.. they just use it... that was frustrating me a lot 😩 bcz i wanted to know what does the Y and X mean in the point slope form equation 😩.. but now after watching u explaining this i got it .. u're a true real savior ❤ thank u so much❤

[@fariefaith1850]

Thank you so much for this video. I like that you explain everything in clear details.

I am a 72 yrs old Dad. Trying to catch up to help my 17 yrs old son with his algebra. Don't die on me just yet! Thanks

[@Gamer-is7pm]

Personally, i have never got this kind of clear explanation anywhere before watching multiple of video lessons and the thing that i was totally impressed by how the y=mx+b formula came from:) much appreciated..

[@MYfriendsknow]

I have watched many, many math videos and yours are the BEST! Thank you PEACE

[@MrOusmane23]

Thanks a lot for your videos teacher.

[@zena101562]

In your video area 10:25/24:27 you said "literally we've done nothing but you did! You revealed a step that was overlooked In my math lab (Pearson) and in my college algebra class because it is assumed that we know to multiply the slope (m) times (x). I kept on getting wrong answers because that step is not revealed but assumed the student know this step. I probably don't make since but you just helped me a lot. Thank you.

Thank you really for your great effort ,,you make me understand in a very easy way

[@Agropelter-700]

Super useful!

[@tresajessygeorge210]

THANK YOU... SIR...!!!

[@user-qf3hy]

Perfect explanation, thank you professor. I had a question : If we are given coordinates of a point and the slope , then is it not better to find the y-intercept ,simply by using the following formula / if y=mx+b , then , b= y-mx ?

[@MathAndScience]

Yes you can totally do that!

[@user-qf3hy]

@@MathAndScience Got it, thank you very much sir, I do appreciate your effort and the pedagogical skill of explaining

[@viktordubowskii695]

Thank you for the upload. I fully understood your lesson plan, and was able to help my nephew, with his algebra homework.

[@dijonstreak]

awesome. dude. !! SO helpful...youdefinitely clarofied this fuzzy subject very sell. thabk YOU. SO. much. a BIG help !!

[@MatthewsLetsie-gv2ef]

Man, you are just great at what you do.👏👏👏

[@shaymaa8007]

enjoyed the lesson, many thanks 😊

[@zaneledindi4210]

Thank you very much to teach me nd I understand well all calculations

[@JasbirGill-nc6po]

Brilliant

[@zermanoesman3032]

Ì understand fully, thank you very much

[@CamiloSanchez1979]

Your explanation is fantastic thank you

[@riyahayden4292]

from question 14.20, I can find y-intercept using y=mx+b

[@alangrace1348]

Thank you 🙏

[@chungubwalya2194]

Loved the lessons ♥️

[@elansmith9291]

this guy is an actual god

[@marinamostert6870]

Can we please have a. tutoral on exponential equations , thank you so much-- ex teacher

[@davidmacatangay4235]

@16:38, 1/2 x is always put as x/2 in the Math score website. Would you consider that to simplify 1/2 x a little further?

[@kimai9]

but what’s the point of finding y-y1 at the first place?

[@mathemathe451]

what is the slope and equations of (1,1)(1,1)?

[@user-abd_almer313]

A(معامل اكس) + B(معامل واي) = C( الثابت : رقم ) المنحدر بالجبر يرمز له بالرمز M او نسميه ميل الخط . تخيل : اربعة خطوط اثنين x موجب وسالب واثنين y موجب وسالب ، رسم بياني ، وخط مستقيم في الجهة العلوية - هذا يسمى zero slope صفر انحدار . وتخيل : نفس الرسم البياني ولكن خط منحدر قليلًا جزئه الصغير في الجهة السفلية والعظيم في الجهة العلوية وهذا يسمى - small slope منحدر صغير . وتخيل : نفس الرسم البياني ، خط طويل يمتد في الجهة العلوية والسفلية للرسم البياني يسمى - Medium slope منحدر طويل . وتخيل : ذات الرسم البياني ولكن الفرق ان المنحدر هذه المرة منحدر جدًا ومقارب إلى التعمد طولًا ويسمى - High slope منحدر مرتفع . - المنحدر غير محدد . وهو كبير بشكل لانهائي . M = Rise\Run = y²-y¹\x²-x¹ y= mx + b نقطة المنحدر y-y¹=m(x-x¹)
