Albedo Inc. manufactures high-end replacement telescope lenses for amateur and professional astronomers who are seeking to upgrade the performance of their telescopes. You have just become employed as a staff accountant at Albedo and Jordan Coleman, the controller, has asked you to help with maintenance cost estimation for the lens manufacturing process. You review the manufacturing process and decide that the best cost driver for maintenance costs is labor hours. The data below are from the previous fiscal year for maintenance expense and labor hours:

Month	Maintenance Cost			Labor Hours
1		$2,870		2,630
2		3,150		2,740
3		3,280		2,840
4		3,825		3,265
5		3,640		3,080
6		4,565		3,770
7		3,940		3,320
8		4,940		4,140
9		4,755		3,940
10		5,010		4,125
11		5,080		4,330
12		4,220		3,480

Required:

What is the cost equation for maintenance cost using the high-low method? (Round "constant" to nearest whole dollar. Round "slope" to 2 decimal places. Negative amounts should be indicated by a minus sign.)
