Answer 1

The answer to your problem is, C.
`-(4)/(3)`

Explanation:

Given that, the green line has a slope of
`(3)/(4)`

We would need to find the slope of the red line.

The formula for the slope of perpendicular lines is m1.m2 = -1. The productof the slopes of perpendicular lines is equal to -1.

Since, m1=
`(3)/(4)`

Now,
`(3)/(4)`. M2 = -1

⇒m2 =
`-(4)/(3)`

Thus the answer to your problem is,
`C. -(4)/(3)`
