Standard Form for the Equation of a Line
General Form for the Equation of a Line

Ax + By = C, where A > 0 and, if possible, A, B, and C are relatively prime integers. The standard form is used in some algebra classes for practice in manipulating equations. Otherwise it is used far less often than other forms for the equation of a line.

Note: An alternate standard form, Ax + By + C = 0, is used as part of the formula for distance from a point to a line.
