Example: Solving and Graphing 9y<549y < 54

To solve the linear inequality 9y<549y < 54, apply the Division Property of Inequality. Divide both sides of the statement by the positive number 99. Because the number being divided by is positive, the inequality symbol stays the same, yielding y<6y < 6. The solution is graphed on a number line by placing a right parenthesis at 66 to demonstrate it is not included, and shading all numbers to the left. This solution translates to (,6)(-\infty, 6) in interval notation.
