Two lines are perpendicular if one has a slope that is the negative reciprocal of the the slope of the other.
I think y=1/8x would be the perpendicular line to y=8x-5 if you neglected to include the negative sign on the 1/8. Check and see if that is what you did.

y = 5 and x = 2 are perpendicular.
