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.
