Question

Find the slope of the line containing the pair of points.
(2, -9) and (12,6)

Answer 1

slope =
`(3)/(2)`

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (2, - 9 ) and (x₂, y₂ ) = (12, 6 )

m =
`(6-(-9))/(12-2)` =
`(6+9)/(10)` =
`(15)/(10)` =
`(3)/(2)`
