Before You Begin

This tutorial contains graphing skills found to be required in economics. If you need review in these skills we suggest completing this tutorial early in the course to maximize your chances for success. Most of the information in this tutorial will be familiar to you, but you may not have seen it in a while so the review should be helpful.

To help you use this tutorial on graph skills, each unit contains:

• Explanation -- each unit begins with an explanation of the particular concept that will be covered.
• Example -- the explanation is followed by an example that will be worked out for you step-by-step.
• Practice -- practice is provided to help you determine how well you understand the skills and information presented. Try to do these without looking back at the text. After completing the practice, compare your answers to the solutions provided.
• Detailed Feedback -- this is provided in case your answer to the practice is not correct or if you want to review the solution.
• Additional Practice -- a second practice is provided for each unit if you need further review.

Don't go on with further units of the tutorial until you are confident that you understand the material you have already studied. To help you further, in the tutorial you will find:

• Glossary of terms -- The glossary is a list of important terms. You can access the glossary from the Table of Contents, or through out the tutorial you will find words that are highlighted and underlined. These are linked to the glossary.
