Inequalities Symbols and line graphs

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 … <

Line Graphs  is greater than  is less than

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

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.

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