Question

Find the slope of the line that passes through (23, -30) and (-7, 18).

Answer 1

slope = -
`(8)/(5)`

Explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (23, - 30) and (x₂, y₂ ) = (- 7, 18)

m =
`(18-(-30))/(-7-23)` =
`(18+30)/(-30)` =
`(48)/(-30)` = -
`(8)/(5)`
