Accepted Solution
A:
Answer:Option D is correct that is The Slopes of two lines are negative reciprocals.Step-by-step explanation:Perpendicular lines are the lines which intersect each other at right angle or make 90° angle with each other.we that the Slope of perpendicular lines are equal to -1Therefore, Option D is correct that is The Slopes of two lines are negative reciprocals.
