What is linear equation?

A linear equation has the algebraic form y=mx+b, where m denotes the slope and b the y-intercept. The previous sentence, where y and x are variables, is commonly referred to as a "linear equation in two variables." Ax+By=C is the typical form for linear equations with two variables. A linear equation in standard form is, for instance, 2x+3y=5. Finding both intercepts (x and y) for an equation of this type is not too difficult.
