a linear equation in two variables doesn't involve any power higher than one for either variable. It has the general form Ax + By + C = 0, where A, B and C are constants.
a linear equation is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation, and may be arbitrary expressions, provided they do not contain any of the variables.
Linear equations are a combination of constants and variables. The standard form of a linear equation in one variable is represented as ax + b = 0 where, a ≠ 0 and x is the variable. The standard form of a linear equation in two variables is represented as.
