  • Welcome to the QLAB Understanding Linear Functions Module. This module is designed to strengthen your understanding of linear functions by giving you an opportunity to see how linear functions are used in several disciplines, as highlighted in the “Applications” section(s).

    For those of you who feel rusty on this topic, this module is also a chance for a refresher. We would recommend that you start with the "Learn and Practice" section before doing the "Applications" section(s). Quantitative skills are built with practice, and this module is designed to help you practice using real-world contexts.

    By using this module we hope that you will be able to answer the following questions:

    What information about the behavior of a linear function is contained in the slope and intercept?
    How can graphs of linear functions be used to describe model systems?
    How can you connect the algebraic and graphical representations of linear functions?
    How can graphs of linear functions be used to compare the behavior of systems?

    You can navigate through the materials in the order presented, alternatively if you're looking for a specific piece of content or are coming back to the module for review, you can jump directly into the module at any point.

    Much of the material is presented in a quiz format. However, please be aware that you're not being graded and the questions are there to help you deepen your understanding not to evaluate you.
