Question 261842
I have to solve a depreciation problem I am not sure how to do this I have found the slope it is -6000 the coordinates of two points on the graph I have picked are (1.0,108000)and (2.0, 114000)the cost of the printing press in the year 2006 120,000. the graph shows the depreciation in 6month intervales 
---------------------
Comment: The slope is the change in y for each change of one in x.
Your x changes one, but your y value has increased.  That is not a 
decreasing function.
---
Are you sure you are not supposed to use an exponential function
to show your depreciation?
---
For example, if "y" decreases 8% each 5 years you
could use y = P(0.92)^(t/5) where t is the time in years
and P is the original value of a house.

You might also Google "depreciating function examples" on the web.
