Which pair of slopes represent perpendicular lines?

a. 1/2, -1/2
b. 1/3, 3
c. -1/4, 4
d. -1/5,-5 Best answer and follow :) thank u

Answer 1

The correct answer is C.

Perpendicular lines have opposite reciprocal slopes. This mean you will flip the original number upside down, and change its sign (negative to positive and vice versa). So, the opposite of -1/4 will be 4.
