Slope Calculator
Calculate the slope (gradient) of a line passing through two points. Slope measures how steep a line is - positive slopes go up, negative slopes go down.
Slope Formula
m = (y₂ - y₁) / (x₂ - x₁)
Slope = rise/run = vertical change / horizontal change. A slope of 1 means 45° angle.
Frequently Asked Questions
What does slope represent?
Slope represents the rate of change - how much y changes for each unit change in x. In real life: a roof pitch of 4/12 means 4 inches rise per 12 inches run.
What is undefined slope?
When x₁ = x₂ (vertical line), slope is undefined because you'd divide by zero. Vertical lines have infinite slope.
