What is the slope of the line below.? With the coordinates (8,8) and (5,5)
yarga [219]

To find slope, use the equation:


(y₂ - y₁)/(x₂ - x₁) = slope


Let:


(8,8) = (x₂, y₂)

(5,5) = (x₁, y₁)


Plug numbers into corresponding areas.


(8 - 5)/(8-5) = 3/3


3/3 = 1


The slope of the line is 1, or 1/1 (rise 1, run 1)


hope this helps
