Question

Find the slope of the line that passes through (8, 9) and (6, 10).

Simplify your answer and write it as a proper fraction, improper fraction, or integer.

Answer 1

slope m = -
`(1)/(2)`

Explanation:

calculate the slope m using the slope formula

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

let (x₁, y₁ ) = (8, 9 ) and (x₂, y₂ ) = (6, 10 )

substitute these values into the formula for m

m =
`(10-9)/(6-8)` =
`(1)/(-2)` = -
`(1)/(2)`
