Okay, so we're going to solve this system of equations by graphing.
00:05
In order to do that, i'm going to turn them into slope intercept form, which is y equals mx plus b.
00:11
We have our slope and our y intercept.
00:13
It'll make the graphing a little bit easier.
00:16
So in the first case here, i'm going to add x over so that 3y is equal to a positive x plus 3.
00:24
And then we divide by 3 to all the items there.
00:29
So we get 1 third x plus 3.
00:31
Plus 1.
00:33
This one will do the same thing, but i'm going to subtract x over.
00:37
There'll be a negative x plus 3.
00:41
And then we can divide everything by 3.
00:45
Y equals a negative 1 3 3rd x plus 1.
00:48
So with the y equals mx plus b, we have the y intercept here and the slope is here...
