Question

Find the slope of a line perpendicular to the equation 3x-y=6

Answer 1

`-(1)/(3)`

Explanation:

The slope of a line perpendicular to a line is the negative reciprocal of the slope of the line given.

The equation of the line is:

`3x-y=6`

`y=3x-6`

The slope of this line is 3.

Thus the negative reciprocal would be
`-(1)/(3)`
