Question

∡rst is a right angle. if rs has a slope of 3, what must be the slope of st?

Answer 1

The slope of st is -1/3

Explanation:

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

`m1*m2=-1`

we have

`m1=3`

substitute and solve for m2

`(3)*m2=-1`

`m2=-(1)/(3)`

therefore

The slope of st is -1/3
