Question

What is the slope between the following points?

Answer 1

slope m =
`(2)/(9)`

Explanation:

calculate the slope m using the slope formula

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

let (x₁, y₁ ) = (- 2, 7) and (x₂, y₂ ) = (7, 9) ← 2 points on the line

substitute these values into the formula for m

m =
`(9-7)/(7-(-2))` =
`(2)/(7+2)` =
`(2)/(9)`
