Question

What is the slope of a line perpendicular to the line 12x - 4y = 7?
A. -7/4
B. 7/4
C. -1/3
D. 1/3

Answer 1

The slope of line perpendicular is a negative reciprocal.
First, put your equation into y =mx + b form.
To get your slope ( the m variable in this equation).

Answer 2

3x-7= y thats your stand mx+c = y form. Slope of the perpedicular line will be -1/3

Answer 3

3x- 7/4*

Answer 4

Could you help on another as well?

Answer 5

sure

Answer 6

Write an equation of a line in slope-intercept form that is parallel to x + 4y = 6 and passes through the point (-8, 5)
A.

y=−14x+3
B.

y=−14x+6.75
C.

y = x - 13
D.

y = x + 13

Answer 7

Thank you!

Answer 8

for paralell you slope doesnt change.. cause _ its paralell

Answer 9

-1/4
will be the slope

Answer 10

so it would be B?
