Line Equation Formula

Slope Formula

m = (y₂ − y₁) / (x₂ − x₁)

This formula calculates the slope between two points.

Slope Intercept Form

y = mx + b

m represents slope and b represents y-intercept.

About Line Equation

Slope Intercept Form

The equation of a straight line is written as y = mx + b. Here m represents the slope and b represents the y-intercept.

Finding Equation From Two Points

If two points are known, the slope is calculated first and then substituted into the equation.

Frequently Asked Questions

What is the equation of a line?
