This video tutorial by Mr. Weaver covers module 3, lesson 3 on linearity and continuity of graphs. It explains how to determine if functions are continuous, discrete, or neither, and whether they are linear or non-linear. The lesson includes examples using real-world contexts like book pricing and soccer ball trajectories. It also covers the standard form of linear equations and how to identify linear and non-linear functions using algebraic and graphical methods.
