1. Inequalities Symbols and line graphs

2. Symbols  < is less than  > is greater than  < is less than or equal to  > is greater than or equal to points to the left … try this - with left hand: make an L, then slightly “lean” hand … <

3. Line Graphs  is greater than  is less than

4. More line graphs  is greater than or equal to  is less than or equal to

5. Solving Inequalities  Use the same steps you use to solve for a variable in an equation with an equal sign  Before graphing, be sure to write the solution with the variable on the left hand side.

6. Practice problems 1. m – 12 > 65 2. x + 23 < 14 3. 12 > y – 9 Solve each inequality, check your solution and then graph.
