The owner of Maumee Ford-Volvo wants to study the relationship between the age of a car and its selling price. Listed below is a random sample of 12 used cars sold at the dealership during the last year.

Car				Age (years)				Selling Price ($000)
	1				9				11.6
	2				5				10.0
	3				12				3.2
	4				15				3.7
	5				7				7.0
	6				6				12.5
	7				8				7.8
	8				13				8.4
	9				12				8.4
	10				15				4.8
	11				4				9.2
	12				4				7.3

1. Determine the regression equation. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)

2. Estimate the selling price of an 8-year-old car (in $000). (Round your answer to 3 decimal places.)

3. Interpret the regression equation (in dollars). (Round your answer to the nearest dollar amount.)
