    Hint: a direct variation is y = kx where k is any real number

    that's an inverse variation equation

    since it's in the form y = k/x

    that's a joint variation equation, notice you have 2 variables on one side

    choice B is another inverse variation equation, just in a different form

    2/3x=y y = 2/3x its in the form y = kx where k = 2/3
