Chapter 7 Systems of Inequalities

7.1 Graphing Inequalities Solve for y to put the inequality into slope-intercept form. Don’t forget to flip your sign if you multiply or divide by a negative! Graph the line. If you have an “equal to” sign (≤ or ≥) graph a solid line. If not, graph a dashed line. Shade the solution set. You can test points to determine which side to shade. *The solution is every point in the shaded area.* Examples: 𝑦>9−𝑥 4𝑥−5𝑦≥37 𝑥+ 2 3 𝑦<6 Do pages 416-418

7.2 Systems of Inequalities Graph each inequality The solution is any point where the shaded areas overlap Examples: 𝑦>2𝑥+4 𝑦<4𝑥−7 𝑦>5𝑥+3 𝑦<5𝑥−3 𝑥≥−4 𝑥≥1 𝑦≤𝑥−2 𝑥≤5 Do pages 425-429. Do NOT use calculators for graphing – you need to know how to graph by hand! We will do pages 432-438 together, start on these if you finish!
