consumer price index (CPI)

Suppose that the consumer price index​ (CPI), which measures the cost of a typical package of consumer​ goods, stood at 125.9 in 1990 and 145.9

in 2000.

Let x equal=0 correspond to​ 1990, and estimate the CPI in 1998

CPI in 1998?

CPI in 2001?

(Assume that the data can be modeled by a straight​ line.)

Which linear equation best models the​ CPI?

y=-2x+125.9

y=2x-125.9

y=2x+125.9

Please include steps to clarify
