<PRE><B>Question 206039</B>
The World of Frying Pans buys a computer for 4000 dollars. After 3 years the computer will be worth 400 dollars. What is the linear equation that relates the value of the computer(V) to the age of the computer(a)?
--------------------------------------------------
You have two points relating time and cost: (0,4000), (3,400)
------------------------------------------------
slope: (400-4000)/(3-0) = -1200
---
intercept: v(0) = 4000
-----------------------------
Equation: v(a) = -1200a + 4000
====================================
