Question

The lines below are perpendicular if the slope of the solid line is 4 what is the slope of the dashed line

Answer 1

The slope of the dashed line is
`-(1)/(4)`

Explanation:

Perpendicular lines and slopes:

If two lines are perpendicular, the multiplication of their slopes is -1.

What is the slope of the dashed line

Perpendicular to a line with slope 4, so:

`4m = -1`

`m = -(1)/(4)`

The slope of the dashed line is
`-(1)/(4)`
