Which of the following consists of a pair of perpendicular lines?
a: d = -1/5x - 4; e = 1/5x + 2
b: d = -1/5x - 4; e = 5x + 2
c: d = 1/5x - 4; e = 5x + 2
d: d = -1/5x - 4; e = -1/5x + 2

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
