Question

What is the equation of a line that is perpendicular to 2x + y = -4 and passes through the point (2, -8)?

Enter your answer as a slope intercept equation (y=mx+b) in the box.

Answer 1

y = 1/2 x - 9

Explanation:

y = -2x - 4

slope of a perpendicular line = 1/2

y -(-8) = 1/2 (x-2)

y + 8 = 1/2 x - 1

y = 1/2 x - 1 - 8

y = 1/2 x - 9
