The sales of a company (in million dollars) for each year are shown in the table below, identify the linear regression model in the form y=mx+b.
NOTE: You should consider the value x as the elapsed time. For 2005 this would be 0 years, for 2006 it would be 1 year and for 2012 it would be 7 years.
What is the predicted value of y (in millions of dollars) when the year is 2012?
The correct answer is: 70.4
