Question

Find the slope of a line perpendicular to each given line Y=-4/5x

Answer 1

5/4

Explanation:

If a line is perpendicular to another, its slopes multiply up to -1.

So, we should write x•-4/5=-1

-4x/5=-1

x=-1•(-5/4)

x=5/4

So, we have y=5/4x+b

Slope is just the value before the x, which in this case is 5/4/.
