This is perpendicular vs Parallel slopes.

Question

What is the perpendicular slope and parallel slope of y=8 and x=-7. Also what is the parallel and perpendicular slopes of y=-5 and x=9/10. I've been working on these problems for a while and I'm still having trouble! I need help, plz! If anybody could plz give answers or offer any websites to find the problem, that would be a great help, thx!

Answer 1

y = 8:

This is a horizontal line, so the parallel slope is zero and the perpendicular slope is not defined.

x = -7:

This is a vertical line, so the parallel slope is not defined, and the perpendicular slope is zero.

Now try answering the other 2 problems using this same reasoning.
