Linear equation

Slope–intercept form of linear equation

y = m x + b

Slope

m = t g α

Intercept form of linear equation

\frac{x}{a} + \frac{y}{b} = 1

General form of linear equation

A x + B y + C = 0

Normal Vector

\vec{n} (A, B)

Direction Vector

\vec{v} (- B, A)

Equation of a Line from 2 Points

\frac{y - y_{1}}{x - x_{1}} = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}
