Slope Calculator

Calculate slope, y-intercept, and line equation from two points. Also find angle and percent grade.

Using the Slope Calculator

In algebra, the slope represents the "steepness" or rate of change of a line. This calculator identifies the slope (m), the y-intercept (b), and the full equation of a line (y = mx + b) given any two coordinate points.

How it Works

Enter the coordinates for Point 1 (x₁, y₁).

Enter the coordinates for Point 2 (x₂, y₂).

Technical Formula


                        m = (y₂ - y₁) / (x₂ - x₁)
