Depreciation: linear functions, graphs, slope

Office equipment was purchased for $20,000 and is assumed to have a scrap value of $2,000 after 10 years. If its value is depreciated linearly (for tax purposes) from $20,000 to $2,000:
(A) Find the linear equation that relates value (V) in dollars to time (t) in years.
(B) What would be the value of the equipment after 6 years?
(C) Graph the equation for t between 0 and 10.
(D) Write a brief verbal interpretation of the slope of the line found in part (A).
