Question

If the slope is 7/3, how do you find the perpendicular slope and the parallel slope?

Answer 1

The parallel is `7/3` The negative inverse of `7/3` is the perpendicular slope.

Explanation:

Lines that are parallel have the same slope.

Lines that are perpendicular are negative inverses of each other so

`7/3 xx - 3/7 = -1`

and you can find this by dividing `-1` by `7/3` and `-1-:7/3=-1xx3/7=-3/7`

So the slope of the perpendicular any where along the line is

`-3/7`
