Since an inequality has multiple solutions, we graph the solution set on a number line. Use open circles for < or > and closed circles for <= or >= . It is always a good idea to choose a value from your shaded part of the number line and test it in the original equation to make sure it's a solution. Turn all improper fractions into mixed numbers to see where they go on the number line. Remember that the inequality "alligator" will eat the larger number!
