Lesson objective: Graph the solutions to inequalities on a number line.

This lesson helps to build procedural skill with graphing the solutions to inequalities. The number line is used here because it is the appropriate place to graph a solution set in one dimension. This work develops students' understanding that there may be an infinite number of numbers in the solution to an inequality, which can all be graphed on a number line.

Students engage in Mathematical Practice 7 (Look for and make use of structure) as they solve and graph the solutions to inequalities.

**Key vocabulary:**

- coefficient
- constant
- denominator
