After watching the video above on graphing, you need to match the inequality statements below in the document below with their corresponding graphs. [|3.1 wikispace journal.doc] In your wikispace journal, explain your entire thought process (from your first match to your last) and how you narrowed down the choices and knew which graph matched which inequality statement.
 * [|Graphing Simple Inequalities] **


 * Group 1: Algebraic Representations**

1.) D its going to the right. 2.)A its going to the left. 3.)C both going in the same direction. 4.)E going in diffrent directions. 5.)F 6.) B

Looking at the shaded graph in the document below, you need to identify a point that is a solution to the system and explain how you know it is a solution by looking at the graph. Also, identify a point that is a solution to only one of the inequalities, but NOT a solution to the system. Explain how you might test a point to determine whether it is a solution to the system or not?

[|3.4.doc] // point(-2,4) because thats where the two intersect. (0,5) is a solution to only one because only the blue line crosses it. //

=== **You want to open your own truck rental company. You do some research and find that the Motor Masters truck rental companies in your area charge a flat fee of $40 plus $0.30 for every mile driven. In your classroom binder, write an equation for the cost of renting a truck from Motor Masters rental company. Also in your classroom binder, create a graphical representation of the cost of renting a truck from Motor Masters. Be sure to label both the x and y-axis in context.** ===

A.) In your wikispace journal, explain what you would need to change about the graph and the equation if you wanted to show the possible costs for a company who was charging LESS than Motor Masters. //i would need to change the amount of flat fee and lower the amount of every mile driven.//

B.) You want to charge less for your truck rentals so you can advertise your lower rate and get more business for your company. In your online journal, explain the following:


 * If you can only change one cost item (either the **flat fee** OR the **mileage fee**), which would you change and why? How would this change help your company charge customers less? Remember to think about which change would be better for the customers and which change would be better for your company... even though any change will be better advertising for your company. Be sure to include the new equation that you have chosen to charge with your new adjusted price.

//I would change the mileage fee because if you pay less for the miles it will end up being less and you wouldnt have to worry how much miles you use because it will be cheaper especially for people who use up alot of miles. for the company it would be better too because we would still be getting the flat fee of 40$//
