Question

What is the equation of the line perpendicular to 2x + y = 0 that passes through the point (2, 2)?

A. y = -2x + 6

B. y = -1/2x + 3

C. y = 1/2x + 1

D. y = 2x - 2

Answer 1

2x + y = 0
y = -2x
slope = -2

Option C:
y = 1/2x + 1
Slope = 1/2 (perpendicular)

At (2,2), x = 2
y = 1/2(2) + 2 = 2

Answer C
