Slope Calculator
Find the slope of a straight line through two points, the rise divided by the run.
A slope of 2 means the line rises by 2 units for every 1 unit it moves to the right, so the line climbs steeply upward.
Formula
Slope = (y2 − y1) ÷ (x2 − x1), the change in y divided by the change in x.
How it works
Enter two points. The calculator subtracts the coordinates, then divides the vertical change by the horizontal change. A vertical line has no defined slope.
Worked example
For example, with points (0, 0) and (4, 8), the slope is (8 − 0) ÷ (4 − 0) = 8 ÷ 4 = 2.
