In this video lesson, students continue interpreting graphs of proportional relationships. An important goal of the lesson is for students to start to interpret the steepness of the graph in terms of the context. They use distance-versus-time graphs to decide which person from a group is going the fastest. They also work with graphs where the scale is not specified on each axis and realize that they can still use graphs to compare rates.
