Comparing Linear Functions: Key Concepts and Techniques

The video tutorial covers how to compare linear functions using graphs, tables, and equations. It explains the steps to find the slope and Y-intercept of each function and create equations for comparison. The tutorial emphasizes the greater impact of slope on function behavior compared to the Y-intercept. An example is provided to illustrate the process of comparing two functions. The session concludes with a summary of the steps and notes for students to add to their notebooks.
