On the next page, construct a plot of the data. Since we are examining how Infant Mortality changes "with respect to" time (or as a function of time), we use time as our independent variable, or x-value, and plot it on the horizontal axis; Infant Mortality Rate as our dependent variable, or y-value, and plot it on the vertical axis. (NOTE:To streamline our calculations later, you may wish to think of 1980 as time x=0, and use x=2 for 1982, x=3 for 1983, etc. With this labeling system, if you later wished to project Infant Mortality Rate
