Linear Inequalitites and Linear Equations
A linear equation is any equation involving one or two variables whose exponents are one. In the case of one variable, one solution exists for the equation. For example, with 2x = 6, x can only be 3.
A linear inequality is any statement involving one or two variables whose exponents are one, where inequality rather than equality is the center of focus. For instance, with 3y < 2, the “<” represents less than and the solution set includes all numbers y < 2/3.
