Slope Calculator

Calculate slope and line equation from two points

slopelineequation

📖 How to Use

Enter the coordinates of the first point (x₁, y₁)
Enter the coordinates of the second point (x₂, y₂)
Click Calculate to see the slope, line equation, and y-intercept

📐 Formula

Slope m = (y₂−y₁)/(x₂−x₁)
Line equation y = mx + b
Intercept b = y₁ − m×x₁

❓ FAQ

What if both points are the same?▾

The slope is undefined when the two points coincide — you need two distinct points.
