So i want to graph the solution to y is less than or equal to negative 4x minus 7, and y is greater than 3x plus 4.
00:12
So let's graph that system.
00:16
I'm going to start with the first one.
00:17
I'm going to color this one blue.
00:20
I'm going to go to negative 7 on the y -axis and put a point, and then my slope is negative 4, so i'm going to go up 4 and left 1.
00:32
And then i can go up 4 and left 1.
00:41
Because that's a less than or equal to, i'm going to connect those points with a solid line.
00:50
And now i have to worry about shading, so i'm going to pick a test point.
00:54
If i pick 0, 0 and substitute it, i get 0 is less than or equal to negative 7, which is not true...
