    Answer:

    The correct answer is must have a positive slope.

    Step-by-step explanation:

    The coefficient of determination varies between -1 to 1. It shows the how strong is the relationship between two variables.

    Coefficient closer to -1 indicate negative relationship and that y decreases with increase in x and the regression equation has a negative slope.

    Coefficient closer to 1 indicate positive relationship and that y increases with increase in x and the regression equation has a positive slope.

    Coefficient closer to 0 indicate that there is no possible relationship between the variables under consideration. It is not possible to construct a particular regression equation.
