The Consumer Price Index (CPI), which measures the cost of a typical package of consumer goods, was 202.2 in 2011 and 244.6 in 2016. Let x = 11 correspond to the year 2011 and estimate the CPI in 2014 and 2015. Assume
that the data can be modeled by a straight line and that the trend continue indefinitely Use two data points to find such a line and then estimate the requested quantities

Answer 1

Answer:

y = 8.48x + 108.92227.64236.12

Step-by-step explanation:

According to given we have (x, y) pairs:

(11, 202.2) and (16, 244.6)

Work out the equation of the line.

Find the slope:

m = (244.6 - 202.2)/(16 - 11) = 8.48

Find the y- intercept using one pair of coordinates:

202.2 = 8.48*11 + bb = 202.2 - 93.28b = 108.92

The line is:

y = 8.48x + 108.92

Find the value of y when x = 14 and x = 15:

y = 8.48*14 + 108.92 = 227.64y = 8.48*15 + 108.92 = 236.12

y = 3(4) + 10 = 12 + 10 = 22

y = 3(5) + 10 = 15 + 10 = 25

We can simplify on both sides by x² + 1 :

x = x²

x - x² = 0

x(1-x) = 0
