Question

Select the pair of equations whose graphs are perpendicular.

A.
2x – 8y = 9
12x – 3y = 7

B.
3x + 6y = 8
y = 2x – 8

C.
y = 2x – 7
x + y = 3

D.
2y = –3x + 5
2x + 3y = 4

Answer 1

I need a response like ASAP

Answer 2

Perpendicular equations have inversed slopes.
Change the the equations and compare which one has the inverse slopes.
Example of perpendicular equations:
y = 3x + 5
y = -1/3x + 5

Answer 3

@shamil98 How can i change the equations though??

Answer 4

Solve for y.
This will get them into slope-intercept form.
y = mx + b
where m = your slope.

Answer 5

okayy thank you
