average debt per capita in thousand dollars

[dmnevarez]

the public debt increased at a relatively constant rate from 1986 to 1996. The following table gives the average debt per capita (in thousand of dollars) for selected years.

years (t) d, average debt per capita in thousands of dollars
1986 9
1988 11
1990 13
1992 16
1994 18
1996 20

Let d =f(t) represent the average debt per capita (in thousands of dollars) and let the input t represent the number of years since 1986 (t=0).
Use the linear regression features on your calculator to find an equation for f(t). Use you equation to answer the following questions.

a. Find the d-intercept of your linear model. What does it mean in terms of the average debt per capita?
b. Find the t-intercept of your linear model. What does it mean in terms of the average debt per capita?
