Understanding This Calculator

Slope Formula

The slope (m) of a line characterizes its direction and steepness.

m = (y₂ - y₁) / (x₂ - x₁)

Example 1

Points: (1, 2) and (3, 6)

  • numerator: 6 - 2 = 4
  • denominator: 3 - 1 = 2
  • Slope: 4 / 2 = 2

Example 2

Points: (0, 0) and (4, 4)

  • numerator: 4 - 0 = 4
  • denominator: 4 - 0 = 4
  • Slope: 4 / 4 = 1 (45° angle)

How to Use

  • Enter two points on the line.
  • Get slope and equation.
