Question

MN has a slope of 4/5 and PQ has a slope of -4/5.Are the lines parallel, perpendicular, or neither?

Answer 1

Neither

Explanation:

MN: slope = 4/5

PQ: slope = -4/5

Two lines are parallel when their slopes are equal but their y-intercepts are different.

Two lines are perpendicular when their slopes are negative reciprocals of each other.

The negative reciprocal of 4/5 (MN) is -5/4

PQ -4/5

-5/4
`\\eq` -4/5

therefore the lines are Neither
