Question

Consider the following equation.

y = - 15
Which of the following lines is perpendicular to the one above?
OA
y = - - 20
ОВ.
y =
21 – 15
OC.
y = - + 19
OD
y = 1 + 14

Answer 1

A

Explanation:

To find the perpendicular line you need to find the negative reciprocal of 4/7x which is -7/4x, so A is the correct answer
