[Jacqueline]

LUV U! A LOT easier! never learned this method before.

Thank you very much!! This is very helpful !!

[sonnethmooreth]

Wow thank you! I have a pretty big test on stuff like this tomorrow, so this is a big help!

[killer]

thanks for makng this video beause you heped me an i and trouble on this

[supergood]

this help me a lot younger generation teach younger generation

Because when finding the Y intercept only, you make the X equal zero. When looking for the X intercept you make the Y zero.

you plug the 3=x into the problem 7(3)-3y=6 then 21-3y=6 then solve for y

Your good at teachig better than my teacher

i'm pretty sure everyone is watching this only because he's cute.

[shineeshepf]

my profesor always give a problem that get an answer fraction he even let us check if our answer is wrong and i hate frations in knowing what the x or y is

[hannahmarlow]

thank you so much I've never understood this my teacher sucks thank you thank you thank you

So how do I know where the line would go, specifically?

[bigguschungus]

if ax + by = c

example C is missing

25x + 30y = 0

i know it will be only 25x

The question is would it be x = - 25 ? (negative)

12/5 = 7 so that's 2 and I am 9 and I am just learning too

iWish we had chalk boads again why cant it come back now its nothibg but technolohy now a days and prometheon boareds im in the 8th grade

[phannylira]

what if you already have the X .. example 7x-3y=6; x=3 ?? HELP

[pizzafreak]

@ILovePenguinsForever cause the chalk is damaging to your lungs and breathing :/

[adeola.ayedun]

I'm still confused.

1. we found Y which equals 12/5 which is basically 2.4
2. we found X which equals 6

if we plug the X and Y value into the equation we have:

2(6) + 5(2.4) = 12
12 + 12 = 12

wrong!! cause 12 + 12 = 24

so what now? :(

Yoy should have arrows on ur graph cause without it you can't say that ur graph is continious.
