Morgan wants to sell his bike and does research online to determine what his selling price should be. He finds $25 bikes of the same bike model listed, along with their ages, in years, and listed prices, in dollars. He finds the equation of the regression line, shown below, where p represents the predicted price and y represents the age of the bike, in years.
$p\ =\ 800\ -\ 50y$ hich of the following is the best interpretation of the rate of change of the equation of the regression line in the context of the problem?
A The price of the bike was originally $800.
B The price of the bike has decreased to $750 .
C As the age of the bike increases by one year, the price of the bike decreases by $50 .
D As the age of the bike increases by one year, the price of the bike increases by $50 .
