So in the following exercises, we want to solve by graphing.
00:04
In order to do that, i want to turn both of these into y equals mx plus b form.
00:09
So for the first equation, i'm going to start by subtracting x over.
00:12
So it's going to be 3y is equal to a negative x plus 4.
00:16
And then we can divide everything by 3.
00:19
So y equals a negative 1 3rd x plus 4 over 3.
00:24
Okay, for this one, i'm going to bring the negative 2, excuse me, negative 2x to the other side.
00:28
So that's negative 6y is equal to a positive 2x plus.
00:31
Plus three, and then i can divide everything by a negative six.
00:36
So two over negative six is going to be the same as a negative one -third.
00:40
We got x, and then minus one -half.
00:44
So we have our two y intercepts, our four -thirds and negative one -half.
00:48
So i can plot those right here...
