3. Housing prices in your neighborhood have been increasing steadily since you purchased your home in 2009. The relationship between the market value, V, of your home and the length of time, x, you have owned your home is modeled by the symbolic rule V(x) = 2500x + 125,000, where V(x) is measured in dollars and x in years. a. Explain how you know that the graph of this symbolic rule is a line. What is the slope of this line? What is the practical meaning of slope in this situation? b. Determine the vertical intercept. What is the practical meaning of this intercept in the con- text of this problem? c. Determine and interpret the value V(8).
