64.1 The Coordinate PlaneUSING A SCATTER PLOT: Many real-life situations can be described in terms of pairs of numbers. Medical charts record both the height and weight of a patient, while weather reports may include both temperature and windspeed. One way to analyze the relationships between two quantities is to graph the pairs of data on a coordinate plane. Such a graph is called a scatter plot.4.1 The Coordinate PlaneSNOWMOBILE SALES: The amount (in millions of dollars) spent in the United States on snowmobiles is shown in the table. Make a scatter plot and explain what it indicates.

4.1 The Coordinate PlaneSOLUTION: Because you want to see how spending changes over time, put time t on the horizontal axis and spending s on the vertical axis. Let t be the number of years since 1990. The scatter plot is shown at the left.ANSWER> From the scatter plot, you can see tat the amount spent on snowmobiles tends to increase as time increases.

4.1 The Coordinate PlaneYOUR TURNThe age a (in years) of seven cars and the price p (in hundreds of dollars) paid for the cars are recorded in the following table. Make a scatter plot and explain what it indicates.
