  2. 2. Solving Linear Inequalities xx 2734 Inequality Linear Expressions
  3. 3. Solving Linear Inequalities The solution of a linear inequality is the set of all values that satisfy the inequality….Intervals!
  4. 4. Properties of Inequalities (p.112)
  5. 5. Properties of Inequalities (p.112) • Like equations, you can do whatever you want, but must do same to all sides. • We want to isolate the variable. • When you multiply or divide an inequality by a negative, you must flip the inequality.
