Question

On a coordinate plane, 2 lines are shown. Line C D has points (negative 2, 4) and (0, negative 4). Line F G has points (negative 4, 0) and (4, 2).
Which statement best explains the relationship between lines CD and FG?

They are perpendicular because their slopes are equal.
They are perpendicular because their slopes are negative reciprocals.
They are not perpendicular because their slopes are equal.
They are not perpendicular because their slopes are negative reciprocals.

Answer 1

Answer:

They are perpendicular because their slopes are equal

Answer 2

Answer:

They are perpendicular because their slopes are negative reciprocals.

Explanation:

Lines need to have slopes that are negative reciprocals of each other in order to be considered perpendicular
