What is the slope of a line perpendicular to the line whose equation is x-3y= -18 Fully simplify your answer.

qwelly [4]

Answer:

-3

Step-by-step explanation:

Isolate -3y by subtracting x from both sides

-3y = -18 - x

Divide everything by -3

y = 6 + 1/3x

Slope is 1/3, and perpendicular lines have the reverse reciprocal slope, so our slope is -3
