Slope Calculator
Calculate the slope Δy/Δx of the line through two points.
How to use
- Enter x and y coordinates for both points.
- Calculate (y2−y1)/(x2−x1).
Capabilities and scope
The tool compares vertical and horizontal coordinate changes to obtain y change per unit x.
How it works
It uses m = Δy / Δx.
Example
Points (1,2) and (3,6) have slope (6−2)/(3−1)=2.
Useful for
- Find linear change between two data points
- Inspect whether a graph line rises or falls and by how much
Before you use it
- A vertical line with x1=x2 has a zero denominator and no finite slope.
Frequently asked questions
What does a negative slope mean?
It means y decreases as x increases along the line.
