Question

Find the slope of (-3, 2) (1, -1)

Answer 1

slope = -
`(3)/(4)`

Explanation:

calculate the slope m using the slope formula

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

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

substitute these values into the formula for m

m =
`(-1-2)/(1-(-3))` =
`(-3)/(1+3)` = -
`(3)/(4)`
