Question

Which pair of equations represents two perpendicular lines?
answers shown in picture. ​

Answer 1

y =1/2x+6

y = -2x+2

Explanation:

Perpendicular line have slopes that multiply to -1

The slopes are negative reciprocals

-4*4 = 16 not perpendicular

1/2 * -2 = -1 perpendicular

1/5 *5 = 1 not perpendicular

2/3 * 2/3 = 4/9 not perpendicular
