Question

What is the slope of a line perpendicular to the line y= 1/5x-1

Answer 1

slope = - 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 =
`(1)/(5)` x - 1 ← is in slope- intercept form

with slope m =
`(1)/(5)`

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

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

Answer 2

M= 1/5

Explanation:

I know because I'm learning this right now in my AP class.
