What You Will Learn to Do: Graph Linear Inequalities on the Coordinate Plane
Did you know that you also use linear equations when you shop online? When you use the option to view items within a specific price range, you are asking the search engine to use a linear inequality based on price. Essentially, you are saying, "Show me all the items for sale between $50 and $100," which can be written as [latex]{50}\le {x} \le {100}[/latex], where x is price. In this section, you will apply what you know about graphing linear equations to graphing linear inequalities.
