You are given two points:  (2000,750) and (2010,1350).  Find the slope of the line segment connecting these two points.  Remember the slope formula?

What amount did Elliot charge in the year 2000?  That's the year in which he started this business, so there's no point in considering years before 2000.  What is the initial value of the fees Elliot charged?  It's the y-value when the year is 2000.
