Which lines are perpendicular?

A) A and B
B) A and C
C) B and C
D) A and D​

Answer 1

Answer:

A and C

Step-by-step explanation:

A)  y = (1/2)x + 2    {Compare with y =mx +b}

slope = (1/2)

C) y = -2x + 4

Slope = -2

$\dfrac{1}{2}*-2 = -1$

When product of two slopes is (-1), then the lines are perpendicular.
