Students investigate the total cost of a private party at three restaurants and then model the cost of a party at each restaurant with the graph of a linear function.
Students are given a chart showing the cost of private parties with different numbers of guests. They are prompted to make a scatter plot of this data, then select the x and y variables, and draw a line through the points and click on two points to draw the line.
