Question

Need help finding the parallel and perpendicular slope

Answer 1

Explanation:

(x₁, y₁) = (19 , -4) & (x₂ ,y₂) = (17, -20)

`Slope =(y_(2)-y_(1))/(x_(2)-x_(1))`

`= (-20-[-4])/(17-19)\\\\= (-20+4)/(17-19)\\\\= (-16)/(-2)\\\\= 8`

m = 8

Parallel lines have same slope.

Parallel slope = 8

Slope of perpendicular line =
`(-1)/(m)`

Perpendicular slope =
`(-1)/(8)`
