Find the equation

Question

Find the equation of a line that is perpendicular to line g that contains (P, Q).

 3x − y = 3P − Q 3x + y = Q − 3P x − y = P − Q x + y = Q − P

Answer 1

It would be great if you didn't use voice-to-text!

Perpendicual lines have opposite, reciprocal slopes, so negatve change in x over change in y.

-(-3 - 0)/(6 - 5) - -(-3)/1 = 3

y - Q = 3(x - P)

y - Q = 3x - 3P

3x - y = 3P - Q
