The windchill (or windchill factor) is a measure of how cold you feel as a result of being exposed to wind. Table 64 pro- vides some data on windchills for various temperatures when the wind speed is 10 mph.

Let w be the windchill (in degrees Fahrenheit) corresponding to a temperature of t degrees Fahrenheit when the wind speed is 10 mph.
a. Without graphing, estimate the coordinates of the t-intercept for a line that comes close to the data points. What does that point mean in this situation? If you don€™t see how to estimate the coordinates, construct a scatterplot of the data first.
b. Without graphing, estimate the coordinates of the w-intercept for a line that comes close to the data points. What does that point mean in this situation? If you don€™t see how to estimate the coordinates, construct a scatterplot of the data first
