Answer:
the slope would be equal to -x or -1
Step-by-step explanation:
First rewrite the equation in correct slope intercept form. Subtract x from both sides and then divide both sides by a negative sign.
x - y = 8
-x -x
[tex]\frac{-y}{-} =\frac{-x+8}{-}[/tex]
y= x +8
A perpendicular slope is the inverse of the original slope. If the original slope is 2 then the perpendicular slope would be -1/2. In this problem the original slope is 1. The inverse of 1 is -1
