Slope Formula m = y₂ - y₁ x₂ - x₁ (x₁, y₁ ) and (x₂, y₂ ) Ordered pairs

y₂ - y₁ x₂ - x₁ (x₁, y₁ ) and (x₂, y₂ ) Find the slope of the line that passes thru the points (5, 2) and (8, 4) m= m = 4 – 2 8 - 5 m = 2 3

y₂ - y₁ x₂ - x₁ (x₁, y₁ ) and (x₂, y₂ ) Find the slope of the line that passes thru the points (3, -1) and (-3, 7) m= m = 7 – (-1) -3 - 3 m = 8 -6 m = 4 3 -

y₂ - y₁ x₂ - x₁ (x₁, y₁ ) and (x₂, y₂ ) Find the slope of the line that passes thru the points (1, 5) and (-4, -5) m= m = -5 – 5 -4 –1 m = -10 -5 m = 2 1
