The Washington, DC average temperature in 1960 was 56.3 degrees. In 2012, the Washington, DC average temperature was 61.5 degrees. Let y be the Washington, DC average temperature in the year x, where x = 0 represents the year 1960.

(a) Find a linear equation which could be used to predict the Washington, DC average temperature y in a given year x, where x = 0 represents the year 1960. Explain/show work.

(b) Use the equation from part (a) to estimate the Washington, DC average temperature for the year 2020. Show some work.

(c) Interpret the slope of the equation in part (a). What is the slope and what does it represent in the context of this application involving average temperature?
