So they want us to solve this system by graphing.
00:04
So the first thing i need to do is i need to rearrange my equations so that they are in slope intercept form.
00:12
So for my first equation, i'm just going to move that x over to the side, and i'm going to get y.
00:21
Y is equal to negative x plus 7.
00:26
And then for my second equation, i'm going to have to move x over.
00:34
And then i have to divide by negative 1 in order to get y, positive y, by itself, which is what i want.
00:42
So my y is equal to a positive 1 half x plus 1.
00:51
All right.
00:51
So that is my equations in slope intercept form.
00:55
So these are going to have a solution because they don't have the same slope.
01:00
So let's get to graphing.
01:01
So this first one has a y intercept of positive.
01:08
Which is about right here.
01:12
And the slope is going to be negative 1 over 1.
01:19
So remember slope is rise over run...
