The U.S. Bureau of the Census predicted that the population of Texas would be about 16.6 million in 2011 and then would increase by about 0.42 million per year until 2016. Which of the following linear models predicts the population, y, of Texas (in millions) in terms of x, the number of years since 2011?
y = 0.42x + 16.6
y = -16.6x + 0.42
y = -0.42x + 16.6
y = 16.6x + 0.42
