Question

Which equation has a graph parallel to the graph of 7x=14y-8

A y=-2x-7
B y=-1/2x+4
C y=1/2x+1
D y=2x+9

Answer 1

C

Explanation:

Parallel graphs have the same slope. To find the slope of 7x=14y-8 convert it to y=mx+b.

7x=14y-8

7x+8=14y

7/14 x + 8/14 = y

1/2 x +4/7 = y

The slope here is 1/2. And C has the same slope of 1/2. They are parallel.
