Question 130110
  The value of a home bought in 1990 appreciates, or increases as time passes. Seven years after it was bought, the house was worth $165,000. Twelve years after the purchase of the house, the house was worth $180,000.
-----------------------
You have two points (7,165000), (12,180000)
slope = 15000/5 = 3000
---------------
165000 = 3000*7 + b
b = 144000
-----------
EQUATION:
value = 3000(years after purchase) + 144000
---------------
b. Estimate the value of the house in the year 2005, which is 15 years after the purchase of the home.
V(15) = 3000*15 + 144000
V(15) = 45000+144000
V(15) = 189000
