Question

The slope of a line is -1/3. Find the slope of a line that is perpendicular to this line. Help please, correct answers and an correct explanation

Answer 1

slope = 3

Explanation:

Given a line with slope m then the slope of a line perpendicular to it is

`m_(perpendicular)` = -
`(1)/(m)`

Given m = -
`(1)/(3)`, then

`m_(perpendicular)` = -
`(1)/(-(1)/(3) )` = 3
