Suppose that the consumer price index(CPI)

Suppose that the consumer price index (CPI), which measures the cost of a typical package of consumer goods, stood at 129.3 in 1990 and 159.3 in 2000. Let x = 0 correspond to 1990, and estimate the CPI in 1998 and 2002. (Assume that the data can be modeled by a straight line.) Which linear equation best models the CPI? O A. y= - 3x + 129.3 O B. y= 3x - 129.3 O C. y= 3x + 129.3 In 1998, the CPI would be approximately (Type an integer or a decimal.) In 2002, the CPI would be approximately (Type an integer or a decimal.)
