The Consumer Price Index (CPI), which measures the cost of a typical package of consumer goods, was 223.2 in 2011 and 241.3 in 2016. Let x=11 correspond to the year 2011 and estimate the CPI in 2012 and 2013 . Assume that the data can be modeled by a straight line and that the trend continues indefinitely. Use two data points to find such a line and then estimate the requested quantities. Let y represent the CPI. The linear equation that best models the CPI is nothing. (Simplify your answer. Use integers or decimals for any numbers in the equation. Round to the nearest hundredth as needed.)

In 2012, the CPI would be nothing. (Type an integer or a decimal rounded to the nearest hundredth as needed.)

In 2013, the CPI would be nothing. (Type an integer or a decimal rounded to the nearest hundredth as needed.)
