7. 4.1 The Coordinate Plane
USING 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.

8. 4.1 The Coordinate Plane
SNOWMOBILE 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.

9. 4.1 The Coordinate Plane
SOLUTION: 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 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.
