Question

If r is a linear function with a slope that is not equal to zero, which of the following is always true of its inverse function?

Its slope is the negative reciprocal of the slope of r.
Its slope is the reciprocal of the slope of r.
Its y-intercept is the negative reciprocal of the y-intercept of r.
Its y-intercept is the reciprocal of the y-intercept of r.

Answer 1

the answer is Its slope is the reciprocal of the slope of r.

Answer 2

Option 2 is correct.

Explanation:

We have given a linear function say r

And we need to tell relation between slope of linear function and its inverse function.

If we have a linear function say y=kx

Then its inverse will be x=y/x

Therefore, the slope of inverse will be slope of r the linear function.
