Look at a few points and then connect them with straight lines.

graph{-|x+10| [-12, -8, -3, 1]}

The most important point is $(-10,0)$ it is where the argument of the absolute value function is 0.

move one either side of this point:

$y = -|-11+10|$

$y = -1$

$y = -|-9+10|$

$y = -1$

You and use the points, $(-11,-1), (-10,0), and (-9,-1)$ to obtain the inverted v shape that is expected.
