What is the slope of a line perpendicular to the line whose equation is 4 x − 2 y = 20 . Fully simplify your answer.

Question

What is the slope of a line perpendicular to the line whose equation is 4x−2y=20 Fully simplify your answer.

Answer 1

4x - 2y = 20

-2y = -4x + 20

y = 2x - 10

Slope of perpendicular is -1 /2
