So many answers....TRUST ME mine's right..the answer is
-1/20
if you want to know why...because when a number is reciprocal of some number, the two numbers multiply together equals 1. (-1/20)*(-20)=1
and, when two slopes multiply together equal -1(negative reciprocal), then they are perpendicular..
