Question

What is the equation of the line that is perpendicular to y = 2x – 4 and has a y-intercept of –2?
A.

x + 2y = –4
B.
y=-1/2x+2
C.
y=-2x-2
D.

2x + y = 2

Answer 1

so a perpendicular slope should be the opposite reciprocal

Answer 2

so the slope should be -1/2

Answer 3

so it will be b

Answer 4

since the form in y=mx+b

Answer 5

thanks so much!!

Answer 6

Welcoem!!
