the consumer price index (cpi), which measures the cost of a typical package of consumer goods, was 228.6 in 2011 and 241.8 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 .
(simplify your answer. use integers or decimals for any numbers in the equation. round to the nearest hundredth encoded
