Question

Lines cand dare perpendicular. If the slope of line c is -4, what is the slope of
line d?

Answer 1

slope of line d =
`(1)/(4)`

Explanation:

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

`m_(perpendicular)` = -
`(1)/(m)` = -
`(1)/(-4)` =
`(1)/(4)` ← slope of line d
