Mathematics / Linear equations in two variables

Mathematics / Linear equations in two variables

A linear equation is an algebraic equation that contains terms which can either be constants or variables. The variables can only be of the first power.

A linear equation in two variables is of the form ax + by + c = 0, where x and y are variables and a, b and c are real numbers. Additionally a and b are non zero.

The graph of a linear equation in two variables plotted on a Cartesian plane is a straight line.
