VocabularyGraph of an inequaltiy:

The set of points on a number line that represent all solutions of the inequality 

Equivalent inequalities:Two inequalities that have the same solution(s)

Example 1: Graph an Inequality in One Variable

Example 2: Use Subtraction to Solve an InequalitySolve x + 11 < 7. Then graph the solution.

Example 3: Use Addition to Solve an InequalitySolve  ­8 > n ­ 19. Then graph the solution.

Solve and graph the following inequality.

1)  14 + x > 24 2)  8 < x + 3

Try It Solve the inequality. Then graph the solution.
