#### Vocabulary

Residual, line of best fit, least squares, scatter plot, extrapolate, linear

#### About the Lesson

Is there any relationship between location and price on the Monopoly board? Students reason through a relationship by considering the amount by which properties increase as they move around the board. Simplistically put, Mayfair is 40 squares from Go and costs \$400, so a good starting point is to assume the relationship is directly proportional to arrive at y = 10x. Students work on the relationship from this point using all the available data to determine a more appropriate relationship including how to quantify the accuracy of their rule. Using the skills developed; students explore the relationship between price and rental return.
