Movie Lines

This Movie Lines lesson plan also includes:

Get in line to buy a movie. Given a table representing the cost of a number of DVDs, pupils plot the points to analyze the relationship. They determine the meaning of the slope and the y-intercept within the context and find values beyond the table. Using a second set of DVD prices, scholars compare the two relationships.
