How to find the slope of the line

The slope, m is calculated using the points on the graph (1, -2) and (2, 1)

m = (y₀ - y₁) / (x₀ - x₁)

m = (1 - (-2)) / (2 - 1)

m = (1 + 2) / (1)

m = 3

Using points (3, 2) and (1, -2)

m = (y₀ - y₁) / (x₀ - x₁)

m = (2 - (-2)) / (3 - 1)

m = (2 + 2) / (2)

m = 2

Using points (2, 1) and (1, 4)

m = (y₀ - y₁) / (x₀ - x₁)

m = (1 - 4) / (2 - 1)

m = (-3) / (1)

m = -3

Using points (6, 5) and (3, 1)

m = (5 - 1) / (6 - 3)

m = 4/3

Using points (-3, -5) and (-3, -6)

m = (-5 - (-6)) / (-3 - (-3))

m = (-5 + 6) / (-3 + 3)

m = 1/0 = undefined
