Slope Formula
m = y₂ - y₁x₂ - x₁
(x₁, y₁ ) and (x₂, y₂ )Ordered pairs
y₂ - y₁x₂ - 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 - 5m = 2 3
y₂ - y₁x₂ - 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 - 3m = 8 -6
m = 4 3-
y₂ - y₁x₂ - 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 –1m = -10 -5
m = 2 1
