Direction and steepness of the line

Slope is rise over run: the change in y divided by the change in x. A vertical line has an undefined slope because the run is zero, and a horizontal line has a slope of exactly zero. The perpendicular slope is the negative reciprocal.

Quick Tool Overview

The Slope Calculator finds the gradient between two points and everything that normally follows in the same question: the line in slope-intercept and standard form, the angle of inclination, the distance between the points, their midpoint and the perpendicular slope.

About the Slope Calculator

Enter two points and get the slope between them, together with everything that normally follows in the same question: the line in slope-intercept and standard form, the angle it makes with the horizontal, the distance between the points and their midpoint.

Slope is rise over run — the change in y divided by the change in x — and its sign and size tell you the direction and steepness of the line. Two cases are worth watching for: a vertical line has an undefined slope because the run is zero, and a horizontal line has a slope of exactly zero. The perpendicular slope, which is the negative reciprocal, is shown as well, since it is what the next part of the question usually asks for.

Key features of the Slope Calculator

More than just the slope

Line equation, angle, distance, midpoint and perpendicular slope, because the next part of the question usually wants them.

Slope as a fraction

Rise over run is shown in lowest terms as well as as a decimal.

Vertical lines handled

An undefined slope is reported as undefined, with the reason, rather than as an error or infinity.

Two equation forms

Slope-intercept and standard form, since different courses ask for different ones.

The substitution shown

The formula appears with your coordinates in place, ready to copy into working.

How to use the Slope Calculator

  1. 1

    Enter the first point

    Its x and y coordinates.

  2. 2

    Enter the second point

    Any second point on the same line.

  3. 3

    Read the slope

    Rise over run as a decimal and a fraction, with the substitution shown.

  4. 4

    Use the extras

    Line equation, angle, distance, midpoint and the perpendicular slope are all calculated too.

Frequently asked questions

Slope m equals (y₂ − y₁) divided by (x₂ − x₁) — the change in y over the change in x, often remembered as rise over run.
