    a: strong and negative linear association between horsepower and gas mileage

    Step-by-step explanation:

    The relationship between two variables is generally considered strong when their absolute value of r is larger than 0.7. Here the absolute value of r is 0.8687 > 0.7.

    The relationship is negative because r is negative, that is, when one variable increases, the other one decreases.
