Question 879171: Non Wage Earners
The numbers of working age civilians (in millions) in United
States who were not involved in the labor force from 2000 through 2009 are given
by the ordered pairs.

(2000,70.0) (2001,71.4) (2002, 72.7)
(2003, 74.7) (2004, 76.0) (2005, 76.8)
(2006, 77.4) (2007, 78.7) (2008, 79.5)
(2009, 81.7)
A linear model that approximates the data is
y=1.22t+70.4,0≤t≤9
where y is the number of civilians (in millions)and t=0 represent 2000. Plot
the actual data with the model. How closely does the model represent the data?
