Task
You have been recruited by your group to become a master in solving a linear system of equations by either the graphing, substitution or elimination method. You will need to learn and practice your method, as well as teach your other group members what you have learned. Then as a group, you will find or create a real-world problem involving a decision that needs to be made (like which cell phone provider to choose) that can be solved using a linear system of equations. You will then present this problem to your entire class, as if you were giving an office presentation, complete with visuals and enthusiasm, helping them decide.
To the right is a copy of the rubric that will be used to assess the work completed. There is another copy of the rubric under the evaluation tab, though it may be a good idea to open and print a copy of the rubric now for use during the webquest.

To the right is a copy of the student sheet outlining all of the steps you will complete during this webquest. You do not have to print this, as all components are tabs above, however, if you would like a paper copy, I have made this available to you.

Standards addressed in this webquest:Massachusetts Curriculum Frameworks-
8.EE - Analyze and solve pairs of simultaneous linear equations.
a. Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.
c. Solve real-world and mathematical problems leading to two linear equations in two variables. For example, given coordinates for two pairs of points, determine whether the line through the first pair of points intersects the line through the second pair.
