Question

Perpendicular lines , If the green line is 3 over 4 what is the red line NEED answers

Answer 1

I think that you meant the green line's slope is $\frac{3}{2}$.

Perpendicular lines have slopes that are opposite reciprocals of each other.

Since the slope of the green line is $\frac{3}{2}$, the slope of the red line must be $\frac{-2}{3}$, because you flip the fraction and change the sign essentially.

So the slope of the red line is -2/3.

Answer 2

-2 over 3
there is the answer
