The table lists the price P of a

first-class postage stamp for selected year’s t.

t 1963 1975 1987 2002 2007

p $.05 $.13 $.25 $.37 $.41

(a) Find the slope of each line segment connecting consecutive data points in the table. Can these data be modeled with a line? Explain.

(b) Does the polynomial 0.835t – 1635 model the

data in the table exactly? Explain

changes in p(cents): 8 12 12 4

changes in t(years): 12 12 15 5

slope on interval(cents/yr): 3/2 1 5/4 5/4

No single line models the data exactly

oops. I wrote the slope reciprocals (years/cent). Still no single line fits all the data points.
