Question

Suppose that a company has just purchased a new computer for $2800. The company chooses to depreciate using thestraight-line method for 4 years.(a) Write a linear function that expresses the book value of the computer as a function of its age.V(x)=0(Type your answer in slope-intercept form.)

Answer 1

1) Gathering the data

$2800

4 years

V(X)=0

2) Writing a Linear function that expresses this devaluation according to the time. In the slope-intercept form.

y=mx+b

As we're dealing with devaluation or depreciation of the value of that computer over time, we have to write -4x, since each year the value is decreasing. Hence, We can write:

V=2800-4x

3) As we can see this straight line:

Of that linear function. In this case, the line stops at x=0. It does not go under the x-axis.
