Problem Statement
The question gives us an equation that gives us the value of a computer after its initial value at purchase. The equation given is:

We are asked to find:
a. The y-intercept and its meaning.
b. The slope and its meaning
Solution
To solve this question, we simply need to compare the equation given to the general slope-intercept equation. The general slope-intercept equation is given by:

With this equation, we can compare with the equation given in the question:

Thus, let us answer the questions:
a. The y-intercept and its meaning:
The y-intercept is 3200.
When we vary the time variable in the equation given, we can get a sense of what this y-intercept means. This is done below:
