Which lines are perpendicular to the line y-1=1/3(x+2)? Check all that apply

Find the negative reciprocal of the slope of the original line.

M perpendicular=−3

ionnno i think is dat

7

step-by-step explanation:

the answer would be 7

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
