Question

i'll fan and medal it's only one question please help me!


Select the pair of equations whose graphs are perpendicular.

A.
y = 2x – 7
x + y = 3

B.
2y = –3x + 5
2x + 3y = 4

C.
3x + 6y = 8
y = 2x – 8

D.
2x – 8y = 9
12x – 3y = 7

Answer 1

one second

Answer 2

if you put some effort into it you would know that perpendicular lines have the same slope

Answer 3

agreed its easy if you know the little tricks.

Answer 4

wait i said that wrong i meant parrelel lines have same slopes

Answer 5

The answer is C but you need to know these things to pass...
