Question

Determine the value of”k” when the lines y=k/3x+2 and y=1/4x+2 are perpendicular.

Answer 1

Answer:

k = -12

Step-by-step explanation:

When lines are perpendicular, their slopes are the opposite reciprocal of each other.

The opposite reciprocal of $\frac{1}{4}$ is -4

$\frac{k}{3}=-4$

k = -12
