Analyzing Functions and Rates

This video tutorial covers Math 8 Unit 5 Lesson 8, focusing on linear functions. It begins with an introduction to linear functions and graph ordering, followed by a discussion on proportional relationships using Jada's earnings as an example. The tutorial then explores unit conversion from feet to yards using linear functions. It analyzes water levels in tanks through linear equations and compares savings growth rates between two accounts. The lesson concludes with a summary and homework discussion.
