Formula

Slope = (y2 - y1) / (x2 - x1).

Use Case

Helpful in algebra, coordinate geometry, and graph analysis.

Tip

If x1 and x2 are the same, the line is vertical and the slope is undefined.

Slope Calculator Guide

Find the slope quickly from any two coordinate points.

How the Formula Works

Slope is calculated as the change in y divided by the change in x between two points (rise over run). A positive slope rises left to right, a negative slope falls, a zero slope is flat, and an undefined slope is a vertical line.

Common Uses

Used in algebra and coordinate geometry coursework, and practically for describing the steepness of roads, ramps, or roofs.

Important Note

Vertical lines have an undefined slope.
