Chapter 3.6, Problem 10PE
The average daily temperature in January for cities along the eastern seaboard of the United States and Canada generally decreases for cities farther north. A city's latitude in the northern hemisphere is a measure of how far north it is on the globe.
The average temperature, y (measured in degrees Fahrenheit), can be described by the equation
a. Use the equation to predict the average daily temperature in January for Philadelphia, Pennsylvania, whose latitude is
b. Use the equation to predict the average daily temperature in January for Edmundston, New Brunswick, Canada, whose latitude is
c. What is the slope of the line? Interpret the meaning of the slope in terms of latitude and temperature.
d. From the equation, determine the value of the x-intercept. Round to one decimal place. Interpret the meaning of the x-intercept in terms of latitude and temperature.
