Lesson 56 Graphing Linear Inequalities In Two Variables

Essential Question How can you graph a linear inequality in two variables?A solution of a linear inequality in two variables is an ordered pair that makes the inequality true. The graph of a linear inequality in two variables shows all the solutions of the inequality in a coordinate plane.

EXPLORATION 1

Writing a Linear Inequality in Two VariablesWork with a partner.a. Write an equation represented by the dashed line.b. The solutions of an inequality are represented by the shaded region. In words, describe the solutions of the inequality.c. Write an inequality represented by the graph. Which inequality symbol did you use? Explain your reasoning.

EXPLORATION 2

Using a Graphing CalculatorWork with a partner. Use a graphing calculator to graph y \x 3.a. Enter the equation y = \x 3 into your calculator.b. The inequality has the symbol . So, the region to be shaded is above the graph of y = \x 3, as shown. Verify this by testing a point in this region, such as , to make sure it is a solution of the inequality.Because the inequality symbol is greater than or equal to, the line is solid and not dashed. Some graphing calculators always use a solid line when graphing inequalities. In this case, you have to determine whether the line should be solid or dashed, based on the inequality symbol used in the original inequality
