Which equation represents a line which is parallel to the line y-2x=3?

Question

A. y=1/2x-3

B.y=−12x+4

C.y=2x−2

D.y=−2x−4

y=2x−2

Answer 1

Slope-intercept form: y = mx + b., where m = slope.

Two lines are parallel if the slopes are the same and the y-intercepts are different.

 

Putting the equation into slope-intercept form:

 

y = 2x + 3

 

Only C. has the same slope, 2.
