Math is my passion

so the first step is to determine the difference by subtracting year 2009 from year 2004

11.7 - 6.1 = 5. 6

Next you subtract 2009- 2004 which is 5 years.

Next divide 5.6 by 5 = 1.12 increase every year

Next determine the equation which would

(6.1)+ (1.12)(×)

X represents the number of years from 2004

Let me know if you have any questions...
