Question

Which of the following pairs of equations represents lines that are parallel? 

A y = 5 - 2x and y = 5 + 2x

B y = 5 - 2x and y = 5 + ½ x

C y = ½x + 5 and y = 2x + 5

D y = 2 - 5x and y = ½ - 5x​

Answer 1

D

Explanation:

The slope of the parallel lines have the same slope. So since D is the only answer choice with the same slope, the answer is D.
