What if the line is vertical?

If x1 = x2, the tool will report the slope as 'Undefined' because you cannot divide by zero. The angle is 90°.

How do I convert slope to percentage?

Multiply the slope value by 100. For example, a slope of 0.5 is a 50% grade.

Slope Calculator

Slope Calculator Overview

Calculate slope and distance between two points

The **Slope Calculator** computes the steepness (gradient) of a line connecting two points, as well as the distance between them and the angle of incline. The slope `m` is a measure of 'Rise over Run'. ### Key Formulas - **Slope (m)**: `(y₂ - y₁) / (x₂ - x₁)` - **Distance (d)**: `√((x₂ - x₁)² + (y₂ - y₁)²)` - **Angle (θ)**: `tan⁻¹(m)` This tool is critical for algebra (linear equations), physics (velocity vectors), and construction (roof pitch).

How to Use Slope Calculator

**Enter Coordinates**: Input (x1, y1) and (x2, y2).
**Calculate**: Get the Slope (m), Distance, and Angle instantly.
**Interpret**: A positive slope goes up; negative goes down. Zero is horizontal.
