A small business buys a computer for $4000. after 4 years the value of the computer is expected to be $200. for accounting purposes the business uses linear depreciation to assess the value of the computer at a given time. this means that if V is the value of the computer at time t, then a linear equation is used to relate V and t. 1) find a linear equation that relates V and t. 2) sketch a graph of this linear equation. 3) what do the slope and V-intercept of the graph represent? 4) find the depreciated value of the computer 3 years from the date of purchase.
