Use a Relationship to Graph a Line | 8.EE.B.5

The video tutorial explains how to graph a proportional relationship by determining ordered pairs and plotting them on a coordinate plane. The example used is the cost of pens at a school store, where each pen costs $1.50. The tutorial guides viewers through selecting points, plotting them, and drawing a line to represent the relationship. It emphasizes checking the graph for accuracy by plotting additional points. The lesson concludes with a summary of the graphing process.
