Formula
The Slope Calculator uses the formula:
Slope (m) = (y₂ - y₁) ÷ (x₂ - x₁)
Worked example
For example, with x₁ of 1, y₁ of 2, x₂ of 3 and y₂ of 8, the slope (m) is 3.0000.

- Slope
- The steepness of a line, measured as the change in y divided by the change in x.
Frequently asked questions
Slope is the change in y divided by the change in x: m = (y₂ − y₁) ÷ (x₂ − x₁). For the points (1, 2) and (3, 8), the slope is 6 ÷ 2 = 3.
The y-intercept is where the line crosses the y-axis, found from b = y − mx. Together with the slope it gives the line equation y = mx + b.
A slope of zero is a horizontal line. If the two x-values are equal the line is vertical and the slope cannot be calculated.
Using the distance formula √((x₂ − x₁)² + (y₂ − y₁)²), which is the Pythagorean theorem applied to the horizontal and vertical gaps.
Enter the x₁. Enter the y₁. Enter the x₂. Enter the y₂. Read off your slope (m), together with y-intercept (b) and distance between points — the calculator updates automatically, with no button to press.
