The U.S. Bureau of the Census predicted that the population of Florida would be about 17.4 million in 2010 and then would increase by about 0.22 million per year in 2015. Which of the following linear models predicts the population, y, of Florida (in Millions) in terms of x, the number of years since 2010.
y = 17.4x + 0.22
y = -0.22x + 17.4
y = 0.22x + 17.4
y = -17.4x + 0.22
