mertsj · Answer

(5,55250) and (13,68546) are ordered pairs of the function.  Find the slope and tell what it means.  The slope is the rate of change.

Well if it was a graph. You would find the the rate of change using the change vertically divided by horizontally. 

68546-55250=13296

divided by the 8 year horizontal difference

you get $1662

dtan5457 · Answer

or you can use the slope formula which is basically the same thing
