The video tutorial explains how to use graphs to determine if two rates are equivalent. It begins with an introduction to rate comparison using Jen's walking example. The lesson covers understanding ratios, including part-to-whole and part-to-part ratios. It then explains the basics of graphing on a coordinate grid, focusing on plotting points. The tutorial demonstrates graphing Jen's walking rate using time and distance, and further explores graphing with different units, such as hours and miles, to compare rates. The key takeaway is that equivalent rates form a straight line through the origin on a graph.
