Question

On a coordinate plane, 2 lines are shown. Line M N goes through (negative 4, 8) and (negative 4, negative 6). Line K L goes through (negative 8, 2) and (6, 2).
How are lines KL and MN related?

The lines intersect at point K.
The lines are parallel.
The lines are perpendicular.
The lines do not have slopes.

Answer 1

The lines are perpendicular. MN is vertical (x = −4) and KL is horizontal (y = 2), so they meet at a right angle.
