Question

Calculate the slope between (4, -9) and (5, 1) as a fraction

Answer 1

slope =
`(10)/(1)`

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (4, - 9 ) and (x₂, y₂ ) = (5, 1 )

m =
`(1-(-9))/(5-4)` =
`(1+9)/(1)` =
`(10)/(1)`
