I'm not completely sure, but this should be exponential growth.
If so, the equation for exponential growth is: y = a(1 + r)^t
If I substitute them with the information you gave me, then is would look like this:
y = 281.4(1 + 0.02)^t
**t = is the number of years after 2000 (based on your question)**
Finished!
(Kevin) y= k-6 - k minus six
(Melanie) y= 2(k-6) - two times k minus six
K, only got that far... sorry
Slope = Y2-Y1/X2-X1 = 7-(-3)/3-(-2)= 10/5 = 2
