The linear equation is one that contains an equals sign (=) like assigning a definite value to x. Linear inequality uses the application of <, >, ≤,≥ and provides an interval for the possible values of x. The Equations are plotted as straight lines and inequalities as shaded areas on graphs. The Equations are applied in some computations, like speed or distance, but inequalities are applied in comparisons, like budgets or limits. They are applied in math, science, and everyday life.
