Determine Rate of Change in Linear Relationships Using Graphs

This lesson teaches how to determine the rate of change in linear relationships by comparing slopes on a graph. It explains the concept of rate as a ratio of change in output to change in input, using examples of car and plane travel to illustrate positive slopes. The lesson also covers negative slopes, using a biplane and dive bomber to demonstrate how to calculate and interpret them. The importance of direction and scale in understanding slopes is emphasized throughout.
