Accounting A school district purchases a high-volume printer, copier, and scanner for 25,000 dollar After 10 years, the equipment will have to be replaced. Its value at that time is expected to be 2000 dollar. $$\begin{array}{|c|c|c|c|c|c|c|c|c|c|c|c|}\hline t & 0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10\\\hline V & & & & & & & & & & & \\\hline\end{array}$$ a. Write a linear equation giving the value $V$ of the equipment for each year $t$ during its 10 years of use. b. Use a graphing utility to graph the linear equation representing the depreciation of the equipment, and use the value or trace feature to complete the table. Verify your answers algebraically by using the equation you found in part (a).

Key Concepts

Linear Equation Modeling

This concept involves representing relationships between two variables using a straight-line equation, typically written in the form y = mx + b. In many real-world scenarios such as asset depreciation, a linear model is used to express how the value of an asset decreases uniformly over time.

Rate of Change (Slope)

The slope of a linear equation indicates the rate at which the dependent variable changes with respect to the independent variable. In the context of depreciation, the slope is negative, reflecting the consistent decrease in the asset's value each year.

Initial Value (Y-intercept)

The y-intercept in a linear equation shows the starting value of the asset when time is zero. This is crucial in depreciation problems as it represents the original purchase price of the asset before any reduction in value occurs.

Graphical Analysis

Graphing the linear equation is an essential method for visualizing how the asset’s value changes over time. It not only corroborates the algebraic solutions but also allows for a clear understanding of the depreciation schedule by tracing the value at specific time intervals.
