Question

Line a has a slope of -5/4. Like t is perpendicular to s. What is the slope of line t?

Answer 1

Hey there!
The new slope of the perpendicular line t is 4/5.
Whenever you want to find a perpendicular slope and you are given a slope, you simply take the opposite of the reciprocal of the given slope, and that's your new slope.
So, we have:
-4/5 (reciprocal)
4/5 (opposite)

Hope this helps!
