Question

What is an equation of the line that passes through the point (−2,5) and is perpendicular to the line whose equation is y = ½ x + 5?


A. y = 2x + 1
B. y = −2x + 1
C. y = 2x + 9
D. y = −2x − 9

Answer 1

Again. You can use point slope. Except this time the slope is the negative reciprocal of that of the original equation.

Answer 2

this one is just throwing me off with half

Answer 3

Yeah. Just flip the 1/2 to get 2 and make that negative.

Answer 4

so B?

Answer 5

Yeah

Answer 6
