Introducing Graphs of Proportional Relationships

This video lesson introduces graphs as an important way of representing a proportional relationship. Students plot points on the graph from tables and start to see that the graph of a proportional relationship always lies on a line that passes through (0,0). They match tables and graphs of given situations and articulate their reasons for each match (MP3).
