Question

What is the slope of a line perpendicular to the line with equation y = 5x – 2?

5


−15


–2


–5

Answer 1

-
`(1)/(5)`

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x - 2 ← is in slope- intercept form

with slope m = 5

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

`m_(perpendicular)` = -
`(1)/(m)` = -
`(1)/(5)`
