    Answer:

    y = 8(2) = 16

    Step-by-step explanation:

    “If y varies directly as x,” then y = kx, where k is the constant of proportionality.

    Here, when x = 6, y = 48.  This data lets us calculate k:

    48 = k*6, or k = 8.

    Then the pertinent equation is  y = 8x.

    If x = 2, y = 8(2) = 16
