Question

Find the slope of the line through each pair of points. (9, 16) , (14, -12)

Answer 1

slope = -
`(28)/(5)`

Explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (9, 16) and (x₂, y₂ ) = (14, - 12)

m =
`(-12-16)/(14-9)` =
`(-28)/(5)` = -
`(28)/(5)`
