Question

What is the slope of the line perpendicular to x-3y=4

Answer 1

-3

Explanation:

x - 3y = 4 Write in the slope intercept form. Subtract x from both sides

-3y = -x + 4 Divide all the way through by -3

y =
`(1)/(3)` x -
`(4)/(3)`

The slope is the number before the x ( 1/3 )

The perpendicular slope is the opposite reciprocal or -3
