Answer:

Neither.

Explanation:

Parallel equations have the same y-intercept. Perpendicular equations have negative reciprocal slopes.

First, turn x-y=9 into y-intercept form.

x-y-x=9-x

-y = 9 - x

(-y = 9 - x)-1

The equations are now

y = x-9 and

y= -5x+1

They don't share the same y-intercept nor do they have negative reciprocal slopes, so it's neither.
