Fitting Linear Models to Data · Exercise 26

The table shows the year and the number of people unemployed in a particular city for several years. Determine whether the trend appears linear. If so, and assuming the trend continues, in what year will the number of unemployed reach 5?

$$\begin{array}{cc}\text{Year}& \text{Number Unemployed}\\ \text{1990}& \text{750}\\ \text{1992}& \text{670}\\ \text{1994}& \text{650}\\ \text{1996}& \text{605}\\ \text{1998}& \text{550}\\ \text{2000}& \text{510}\\ \text{2002}& \text{460}\\ \text{2004}& \text{420}\\ \text{2006}& \text{380}\\ \text{2008}& \text{320}\end{array}$$

Its source prints no answer for this problem, so there's nothing to check against.
