1. Chapter 7 Systems of Inequalities

2. 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

6. 7.2 Systems of Inequalities
Graph each inequality
The solution is any point where the shaded areas overlap
Examples:
𝑦>2𝑥+4 𝑦<4𝑥− 𝑦>5𝑥+3 𝑦<5𝑥− 𝑥≥−4 𝑥≥ 𝑦≤𝑥−2 𝑥≤5
Do pages Do NOT use calculators for graphing – you need to know how to graph by hand! We will do pages together, start on these if you finish!
