  1. LEARNING GOALS FOR LESSON 3:3 3.3.1 Graph a system of inequalities 3.3.2 Write and solve a system of inequalities 3.3.3 Classify a shape created by a system of lines When you graph multiple inequalities on the same graph, the overlap is the solution. LG 3.3.1 Example 1A: Graphing Systems of Inequalities Graph the system of inequalities.

  2. Graph each system of inequalities. LG 3.3.1 A. Graph each system of inequalities on the graphing calculator. LG 3.3.1 B. Sketch the graph. LG 3.3.3 Graph the system of inequalities, and classify the figure created by the solution region. x ≥ –2 x ≤ 3 y ≥ –x + 1 y ≤ 4 LG 3.3.1

  3. Example 3: Application LG 3.3.2 Leyla is selling hot dogs and spicy sausages at the fair. She has only 40 buns, so she can sell no more than a total of 40 hot dogs and spicy sausages. Each hot dog sells for $2, and each sausage sells for $2.50. Leyla needs at least $90 in sales to meet her goal. Write and graph a system of inequalities that models this situation. d 0 s 0
