Question

What is the slope of the line passing through the point (3, -4) and perpendicular to the line y = 3x + 5? Write your answer as a fraction.

Answer 1

-1/3

Answer 2

if slope of a line is m as in the form y = mx + b then the slope of a line perpendicular to it is -1/m
here im = 3 so the answer is -1/3

Answer 3

y = 3x + 5
Perpendicular slope : m = -1/3
( there's no need to check the point)
