Question

The initial cost of a computer is $3000. After 3 years, the value of the computer is expected to be $1100. A)Write a linear model to represent the data. B)Assuming that there is a linear relationship between the value and the age of the computer, find the value of the computer 5 years after the purchase of the computer. C)what is the meaning of the slope in this linear model?

Answer 1

Let x represent the number of years and
y represent the cost of the computer.

When x = 0, y = 3000
When x = 3, y = 1100

"Linear model" implies a straight line can be assumed.
Find the equation of a straight line knowing the two points (0, 3000) and (3, 1100).
