Question

The equation of line r is y = 3x − 7 Line s includes the point(6, -9)and is perpendicular to line What is the equation to find s ?

Answer 1

y=-.3x-7

Explanation:

So, if you want to find a line perpendicular to another line, you have to put a decimal in front, or make it a reciprocal. In this case, I put a decimal in front to make it both perpendicular, and cross through (6, -9). Nice.
