All right, so we're here to graph x is less than negative 4 on a two -dimensional coordinate plane.
00:05
So the first thing that we're going to do is we're going to graph the boundary line, which is what we would get if we replace this inequality with x equals negative 4.
00:15
And then the less than or the greater than divides it into three regions, right? so first thing i'm going to do is i'm going to find x equals negative 4, 2, 3, 4.

Okay, and the line in this case in two dimensions is going to be a vertical line.
00:31
I'm going to go and graph that.
00:36
Now if we want to graph everything that's less than negative 4 or greater than negative 4, right, that's either going to be on the left or the right -hand side of this vertical line.

And what you typically do is you use a test point to determine what region to shade...
