Question

Find the slope between (-2,3) and (1,-5).

Answer 1

slope = -
`(8)/(3)`

Explanation:

calculate the slope m using the slope formula

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

let (x₁, y₁ ) = (- 2, 3 ) and (x₂, y₂ ) = (1, - 5 )

substitute these values into the formula for m

m =
`(-5-3)/(1-(-2))` =
`(-8)/(1+2)` = -
`(8)/(3)`
