Three vertices of a quadrilateral are (-3, 3),
(-5, -7), (5, -7). Find the coordinates of a fourth
point that would make the quadrilateral a
parallelogram. Justify your reasoning.
IGNORE THE SQUARE ON THE GRAPH a trapezium is a quadrilateral with parallel sides see how you could draw that and match the coordinate to the y in (-3,3) and then use the reciprocal of -3 as the x coordinate your final plot points would be (3,3) plot this point and join up your coordinates.
