Question

What is the slope of the line that passes through the following points: (20,8) (9,16)

Answer 1

slope m = -
`(8)/(11)`

Explanation:

calculate the slope m using the slope formula

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

let (x₁, y₁ ) = (20, 8 ) and (x₂, y₂ ) = (9, 16 )

substitute these values into the formula for m

m =
`(16-8)/(9-20)` =
`(8)/(-11)` = -
`(8)/(11)`
