one idea is make two points from the info they gave you
In 1999, a net loss of $5,000.   make that point (1999, -5000)  (negative because it is a loss)
 In 2009, profit was $75,000     make that  pointc

Find the rate of change of his profit from 1999 to 2009. 
means find the slope between the two points
(1999, -5000)   and (1999, -5000)
