Question

What is the equation of the line in slope-intercept form that passes through the point (–2, 4) and is perpendicular to the line y = –2x + 4?

a. y = -1/2x – 5
b. y=-1/2x-2
c. y=1/2x+2
d. y=1/2x+5

Answer 1

Whats slope of y = –2x + 4?

Answer 2

-2

Answer 3

So can you find the perpendicular slope?

Answer 4

wouldnt that be 1/2

Answer 5

Correct :)
Now after you have the perpendicular slope, plug m = 1/2 and (–2, 4) into point slope form formula:

Answer 6

so would it be y=1/2x+2?

Answer 7

well im confused.

Answer 8

yeah, i figured it out and got y=1/2x+5

Answer 9

Correct answer! You won't be confused if you know the steps to proceed !

Answer 10

thanks!
