    Answer:   (5/9,  -7/6)

    =======================================================

    Explanation:

    Since the center of dilation is (0,0), we multiply each coordinate of point B by the scale factor 1/3.

    The coordinates of point B are x = 5/3 and y = -7/2

    So we have

    (1/3)*x = (1/3)*(5/3) = (1*5)/(3*3) = 5/9 as the new x coordinate

    and

    (1/3)*y = (1/3)*(-7/2) = (1*(-7))/(3*2) = -7/6 as the new y coordinate

    The point (5/3, -7/2) moves to (5/9,  -7/6)
