Question

Calculate the slope of the linear function shown in the graph. Show all work.

Answer 1

slope = - 5

Explanation:

calculate slope m using slope formula

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

with (x₁, y₁ ) = (0, 120) and (x₂, y₂ ) = (10, 70) ← 2 points on the line

m =
`(70-120)/(10-0)` =
`(-50)/(10)` = - 5
