An unknown quadrilateral has these points: A(0,-3) B(6,-3) C(9,1) D(3,1) Based on your discoveries about the slopes of the sides, can this shape be a parallelogram? (hint: compare the slopes of the opposite sides; to be parallel, opposite sides must have the same slope) (1 point) Responses yes; the slopes of the opposite sites are 4/3 and 0 respectively yes; the slopes of the opposite sites are 4/3 and 0 respectively no; opposite sides do not have the same slope no; opposite sides do not have the same slope yes; the slopes of the opposite sides are 5/3 and 0 respectively
