Question

How do you graph the inequality `y> x + 9`?

Answer 1

See below

Explanation:

First, graph it as a regular line, `y=x+9`. Then, in order to find out which side you should shade, you should plug in a point. Let's use `(0,0)` to make things easier.
Plugging in these coordinates for `y` and `x` back into the original inequality would yield the equation `0>0+9 = 0>9`. This is clearly not true, so you would shade the side that does NOT include `(0,0)`. graph{y>x+9 [-12.5, 7.5, -3.36, 6.64]}
