Question 624651: A formula in the form of +y=+mx%2Bb models the average retail price, {y} of a new car {x} years after 2000. Would you expect {m} to be Positive, negative, or zero? Explain your answer.
I think it would be postitive cause when your dealing with new cars there should not be a negative.
Just not sure if that would be right.

.
m (the slope) would be POSITIVE because the cost of new cars are INCREASING with each new model.
