Answer:
-1
Step-by-step explanation: from the equation, x-y=8, make y the subject of the formulae , this gives - y= -x +8
divide all through by (-) sign, this gives y= x - 8
from the last equation above, the slope is the coefficient of x which is 1. since it is perpendicula, the answer is -1
by co efficient, we mean the number multiplying the unknown
