How it works

Slope formula:
m = (y2−y1) / (x2−x1)

Examples

  • (1, 2) to (4, 8) → slope = 2
  • (0, 0) to (3, 3) → slope = 1
  • (2, 1) to (2, 5) → slope = undefined

FAQ

  • What is slope?

    Slope measures the steepness of a line and is calculated as rise over run: (y2−y1)/(x2−x1).

  • What if x1 equals x2?

    Then the slope is undefined because the line is vertical and division by zero would occur.

  • Can slope be negative?

    Yes. A negative slope means the line goes down as x increases.

  • Are my coordinates stored?

    No. Calculations run locally in your browser and are not stored or transmitted.
