Question

What is the slope of the line that passes through the points 9,-1 and 4,11 simplest form

Answer 1

slope = -
`(12)/(5)`

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (9, - 1 ) and (x₂, y₂ ) = (4, 11 )

m =
`(11-(-1))/(4-9)` =
`(11+1)/(-5)` = -
`(12)/(5)`
