Question

Calculate the slope of a line that passes through the points (9, 3) and (19, -17). 10 2 -2 7/5

Answer 1

slope = - 2

Explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (9, 3) and (x₂, y₂ ) = (19, - 17)

m =
`(-17-3)/(19-9)` =
`(-20)/(10)` = - 2
