==============================================

Explanation:

The given equation is in the form with slope

Apply the negative reciprocal to to get . We flipped the fraction and the sign from positive to negative. The perpendicular slope is

With any two perpendicular lines, their slopes always multiply to -1. This is assuming neither line is a vertical line. In this case:

------

We'll now let and

Plug these three pieces of information into the point-slope formula

This points to choice C as the final answer.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
