Method
Slope m = (y₂ − y₁) ÷ (x₂ − x₁). Substitute either point into y = mx + b to find the intercept.
Example
Points (1,2) and (5,10) have slope (10 − 2) ÷ (5 − 1) = 2.
Limits
Check inputs and units. Important academic, financial or professional decisions should be confirmed against an appropriate source.
