The population of a small town in Central Florida has shown a linear decline in the years 2002-2010. In 2002 the population was 47200 people. In 2010 it was 45280 people. A) Write a linear equation expressing the population of the town, P, as a function of t, the number of years since 2002. Include the entire equation in your answer. B) If the town is still experiencing a linear decline, what will the population be in 2012?

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
