Question

15. Determine whether the pair of lines is parallel, perpendicular, or neither.

1
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.

Answer 1

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

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.
