Exploring Recording Techniques with Screencast-O-Matic

The video tutorial introduces students to graphing using function tables. It begins with deriving equations for Trevor and Smith's earnings based on their hourly rates. Students learn to complete function tables and create ordered pairs. The tutorial then guides students through plotting these points on a coordinate plane and analyzing the resulting graphs. The lesson emphasizes understanding the relationship between hours worked and total earnings.
