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.
