The V-shaped graph is inserted. In the region exterior to V, $y<|x-9|$ .

The equation $y=|x-9|$ is the combined equation for

$y=x-9, x>=9$ and

$y=-(x-9), x <= 9$

representing two half lines, above their common point (9, 0).

For any point below these lines, $y<|x-9|$ .

graph{y-|x-9|=0 [-40, 40, -20, 20]}

How do you graph the inequality y<abs(x-9)y<abs(x-9)?
