y = 2x - 5 and y

2x+7

Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

A. The lines are perpendicular because the product of their slopes is - 1.

B. The lines are parallel because the product of their slopes is - 1.

C. The lines are parallel because the slope of both lines is the same,

(Type an integer or a fraction)

D. The lines are perpendicular because the slope of both lines is the same,

(Type an integer or a fraction.)

E. The lines are neither parallel nor perpendicular because neither are their slopes the same nor

is the product of their slopes - 1.

Louisa · Answer 1

C. The lines are parallel because the slope of both lines is the same

Step-by-step explanation:

Parallel lines are formed when 2 lines have the same slope but different y-intercepts. Since the 2 given equations show this, the answer choice is C.
