Let year be the x variable and the home price be the y variable.
Generate a linear function that relates year (x) to home price (y).
Estimate what the average home price was in 2009.
Estimate what the average home price will be in 2035. Discuss your answer.
If this trend continues, estimate what year you would predict the average home price will reach $250,000.
Describe in your own words, what the slope of this function tells you.
Give another example where you might use a linear representation to model change over time.
Hint for a- f: You have two points and you are generating the equation of a line given two points. Your points are of the form (x, y) or more specifically (year, home price).

Hi,
The average home price in Linden Hills, Minneapolis in 2007 was $381,000
The average home price in Linden Hills, Minneapolis in 2011 was $296,000
(0,381,000)
(4,296,000 m = 85,000/-4 = -21,250
Generate a linear function that relates year (x) to home price (y).
 where x is the number of years after 2007
Estimate what the average home price was in 2009. $338,500
Estimate what the average home price will be in 2035. -21250*28 + 381,000
If this trend continues, estimate what year you would predict the average home price will reach $250,000.
250,000 = -21250x + 381,00
-131,000/ -21250 = x = 6.165 2007 + 7 = 2014
