Graph did not make the trip.
The slope of the line is needed to write the linear equation.

From the post, the depreciation rate is  20000%2F5 = 4000 monetary units per year.



THEREFORE, the depreciation function is


    y = 20000 - 4000*x,


where x is the time in years after the starting moment.



In 3 years,  y = 20000 - 4000*3 = 8000.
