Let’s Graph This Line - Step-by-Step….

[@meshelleramsey1397]

I wish you could be my instructor, I always get it when you demonstrate the problem 😀

[@maxoblivion]

50 years ago this material seemed difficult to me and now it seems clear and simple. Either you're a very good teacher or I'm 50 years smarter. Maybe a bit of both would be true.

[@peterpeggycheah7719]

X=4. Y=1 2X=8. 4y=4. 8+4=12. Ans

[@debbies6192]

I am enjoying your videos. Thank you.

[@SuperFerdie1965]

The problem with the intercept method is it doesn't work if b=0. For example, y=5x. All you would get is the point (0,0) twice! In a case like that, I would revise my table and just work out the values of y when x=0 and when x=1. You'd then arrive at the fact that (0,0) and (1,5) lie on the line.

[@hughsonj]

In my math class, our teacher always wanted us to have a set of 3 coordinates for linear equations. I think he did that to prepare us for parabolic equations.

[@alexgrant2931]

Very clear !

[@bravo3541]

Great review for me. Thanks. (I'm helping my grandchildren from great distance)

[@haniefhaider4528]

Again excellent explanation but keep the intro a bit short. Or put some suspense/excitement in it otherwise the class may just doze off.

[@v-gc7257]

Very nice. Thank you

[@davidlloyd3116]

In the UK we always use the formula y=mx+c. I wonder why this is? Not that the letter matters of course!

[@Peakosprey]

It’s the most basic formula for linear equations, it is called slope- intercept form

[@SuperFerdie1965]

Yep. The formula y = gx + i would make more sense!

[@JOKER6979]

Basically X and Y are both equal to 2? Am I correct? 2×2+4×2=12. That's the breakdown I got.

[@donnamaebrigoli9960]

Did u multiply the answer of 4y/4 =12/4 so the answer is y=3?

[@Vicryl007]

This gave me anxiety like when I was in High School Algebra

[@janoszala3078]

using old school it is very simple...if x/2 y is 2, if x is 1 - y is 2.5

[@khietphan725]

Y=-1/2X+3

[@user-eq3er4ny9s]

Why come up with any theories? The only theory is simplicity. 1. If x and y are in the first degree, then the graph is a straight line. 2. Two points are needed to draw a straight line. 3. To simplify arithmetic calculations, we take alternately x and y equal to zero, because multiplying zero by any number will be zero. If the line passes through the point (0; 0), then we substitute any other number instead of x or y, for example 1. that's all. One minute of explanation is enough. For this example, at first it would be nice to simplify it by dividing the left and right sides of the equation by 2 and getting x + 2y = 6. More than 50 years ago, we did it like that.

Thanks. What's the practical use in our daily life? Thank you so much.

[@jesusalvarez6080]

Are you kidding? Time Space and Events are pretty much in your daily life from the time you get up till the time you go back to bed. How long does it take you to get somewhere by plane, by train, by car? ...and so much more including every second of your daily life. How about vaccinated people VS unvaccinated and the number of deaths on both sides? Think of anything graphs apply.

[@silajeep1]

JESUS ALVAREZ why the condescending comment? It was a perfectly legitimate question to ask from someone who is trying to understand maths like myself. I am here trying to learn maths at the age of 58yrs as in school I struggled with it. Why are you here if you already know how to do maths?

[@jesusalvarez6080]

@@silajeep1 I actually had the same question for my teachers and, as simple as that, none could answer it, just like his went unanswered so I thought it was my time to respond, what is so condescending about it? Oh, and to answer your question: because I always loved math, I miss it and it brought me memories as I hardly use it any more but I know what algebra is for.

[@silajeep1]

JESUS ALVAREZ thanks for replying, usually when someone responds by saying "are you kidding?" infers the other person is stupid

[@jesusalvarez6080]

@@silajeep1 Yeah I know what you mean, in all honesty I actually thought Edmund's question was more related to sarcasm rather than one who was seeking knowledge; yet, on the other hand, you could be right, in which case is my bad.

Far too much verbiage and repetition. I explained this to my wife in less than a minute and she got it right away!

Set X to zero then Y is3. Set Y to zero then X=6. Draw a line through those two points. Done.

[@danielcase1046]

The value of X and Y are 2.

[@peterpoint-dujour3299]

Why couldn't I said, 2x-4y=12 then I divided 12by 2x= and have X=6?

[@josephaaron8875]

2 x 4 equals 8 plus 4 x 1 equals 4 equals 12, you only needed the variable of 22 to get the answer, eh!

[@Tim-Kaa]

My 7yo loves this.

[@HackedPC]

7 years old and graphing linear equation ...kidding?

[@theophonchana5025]

2x + 4y = 12 2x + 4y - 12 = 0

[@Garensonic]

y = (-1/2)x + 3

[@donaldgregg9250]

2x2 + 4x2 =12

[@HoratioTalbot771_a]

Cant you just divide both sides of 2x+4y=12 by 2+4. and get x=1. and y=1 ?

[@andtrrrot]

No. The assignment is to graph the line. The solutions are all the points on the line. If you plug 1,1 back into the equation, you can see that it is not a point on that line. 2(1)+4(1) does not =12. Substituting 1,1 back into the equation does not make a true statement. Therefore they are not a solution to the equation.

[@HoratioTalbot771_a]

I thought you were just solving this equation with algebra but I was in correct . If you were. x. and y would both be 1

[@andtrrrot]

12 plus 12 does not equal 12

[@albertchiu655]

the introduction is too long !

[@LK-qz7eh]

Yeah he rambles waaaayyyy too much. He needs to get to solving the problem quicker!

[@robertmontgomery1920]

Why does everyone say it's so clear? You're not teaching anything for example if x was 2 and y was 2 2x+ 4y =12 would also be true so what are you solving here what are you talking about

[@andtrrrot]

That is only 1 solution. A line is made up of an infinite number of points, therefore it has an infinite number of solutions. Besides, the assignment was to graph the line.

[@silajeep1]

andtrrrot lol, yes you are right. Seems like a lot of people forgot to read the title of this video heheh

[@andtrrrot]

@@silajeep1 It's a wonder how many people stop seeing the printed word when they do math.

[@lookingforahookup]

There’s no need for all that.

[@dennislarson9560]

Instead of promoting your agenda and classes, don't spend time explain what else we can do. The table of solutions will do very nicely, three pairs will give the line and confirm it's correctness.

[@MrRackinroll]

I am no math genious but that was to much info. I would never go to you for any math issues. No No RC
