Syllabus

Linear Functions and Equations

Throughout this specialization, we will use functions to help visualize, analyze, and interpret the relationships between variables. In this module, we will start by exploring linear functions. A linear relationship between two variables occurs when changes in one variable correspond to proportional changes in the other. Many physical situations can be modeled using linear functions. We will see examples of how to create and interpret linear functions in the sections that follow.
