Question

Which two equations represent parallel lines?

A. Y=2x-5
B. Y=-1 over 2x +5
C. Y=1over2x-5
D. Y=2x+ 5
And why?

Answer 1

A and D are parallel.

Explanation:

Refer to the slope-intercept equation (y = mx + b).

M = the slope

If the slopes are equal, then the lines are parallel.

The slope for line A is 2, and so is the slope for line D.

Line A and line D are parallel.

Answer 2

A&D

Explanation:

Lines with the same slope are parallel. 2x-5 and 2x+5 have the same slope
