Identify Linear Relationships by Exploring Rectangle Perimeter

The video tutorial explores the concept of perimeter and linear relationships using rectangles. It introduces two methods to calculate the perimeter: adding all sides and using a formula. The tutorial demonstrates how the perimeter changes with additional rectangles, highlighting a constant rate of change, which is a characteristic of linear relationships. Graphs are used to visualize these relationships. The video also addresses common misunderstandings about linear functions and provides examples of non-linear relationships, emphasizing the importance of a constant rate of change in linear functions.
