  1. Introduction to Inequalities
  2. Graph the solution on a number line:
    x=3x = 3
    x3x \ge 3
    xx > 3 3
    x3x \le 3
    xx < 3 3
  3. Graph the solution on the xy-plane:
    x=3x = 3
    x3x \ge 3
    xx > 3 3
    x3x \le 3
    xx < 3 3
  4. Graph the solution on the xy-plane:
    y=2y = -2
    y2y \ge -2
    yy > 2 -2
    y2y \le -2
    yy < 2 -2
