    Don't need the quotient rule because it is 1/4(3x+7)

    Distribute the 1/4. You will get 3/4x+7/4

    Well then, it isn't the derivative.

    so how do I find the deriv after distributing 1/4?

    3/4 is the deriv of f?

    At x = -4, the value of the derivative is 3/4 because the derivative is always 3/4

    Yes. The derivative of a linear function is a constant because the derivative is the slope function and the slope of a line is a constant.
