WebStep by step guide: Inequalities on a number line List integer values in a solution set We can list all of the integer values represented by an inequality E.g. List the integer values represented by 2<8 2 < x < 8 As ‘<’ means less than, the values of x x do not include the values given. ‘ 2 2 ’ and ‘ 8 8 ’ are not included in the solution set. WebMay 4, 2024 · Inequalities can be graphed on a number line. Below are three examples of inequalities and their graphs. Each of these graphs begins with a circle—either an open or closed (shaded) circle. This point is often called the end point of the solution.
