Slope Calculator

Find slope, rise, run, direction, and line equation from two points with this free slope calculator.

Calculate Slope

m = (y₂ - y₁) / (x₂ - x₁) = (11 - 3) / (6 - 2)

How slope is calculated

Slope formula:
m = (y₂ − y₁) ÷ (x₂ − x₁)

Rise:
Change in y-values

Run:
Change in x-values

Line equation:
y = mx + b

Why slope matters

Slope shows how quickly one quantity changes compared to another. It is widely used in algebra, geometry, physics, engineering, and graphing.

It helps describe direction, steepness, and relationships between variables.

What your result means

Your result shows the slope, rise, run, line direction, and equation through the two points. This makes it easier to understand how the line changes across the graph.

A positive slope means the line rises, a negative slope means it falls, zero slope means horizontal, and undefined slope means vertical.

Frequently asked questions

What is slope?

Slope is the rate of change between two points on a line, measured as rise over run.

What does a negative slope mean?

A negative slope means the line goes downward from left to right.

What does an undefined slope mean?

An undefined slope means the line is vertical because the run is zero.

Can slope be written as a fraction?

Yes. Slope is often written as a fraction because it is rise divided by run.
