Identifying Linear vs Nonlinear Functions

The video tutorial explores the differences between linear and non-linear equations. It begins with an introduction to the topic, followed by a detailed discussion on the characteristics of linear equations, such as having a variable with a power of one and being represented in the form y = mx + b. The tutorial then demonstrates graphing both linear and non-linear equations using examples, highlighting the differences in their graphical representations. The session concludes with an exploration of non-linear equations, emphasizing the importance of the variable's power in determining linearity.
