Question

Find the slope of the line represented by the data on the picture

Answer 1

slope = - 4

Explanation:

Calculate the slope m using the slope formula and any 2 ordered pairs from the table.

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 8) and (x₂, y₂ ) = (- 1, 4) ← 2 points from the table

m =
`(4-8)/(-1+2)` =
`(-4)/(1)` = - 4
