(Modeling) Solve the problem.
Amtrak Passengers In 2008 Amtrak had 28.7 million passengers, and in 2012 it had a record 31.2 million passengers.
(a) Find a linear function P(x) = ax + b that models the number of passengers in millions x years after 2008.
(b) Interpret the slope of the graph of y = P(x).
(c) Use P(x) to estimate the number of passengers in 2014.
(d) Assuming trends continue, predict when Amtrak might have 35 million passengers.
