What is the average temperature in Paris?

In 1870 the average ground temperature in Paris was 11.8°C. Since then it has risen at a nearly constant rate,?

• **continued reaching 13.5°C in 1969. a. Express the temperature T (in °C) in terms of time t (in years), where t = 0 corresponds to the year 1870 and 0 ≤ t ≤ 99. (Give your answer in slope-intercept form.) b.During what year was the average ground temperature 12.7°C? (Round your answer down to the nearest year.)

• Answer:

  If the rate is constant, then it rose 1.7 C in 100 years, or 0.017C per year (1.7/100). From there you can find the answers to the questions.
