Question

Three vertices of a quadrilateral are (-3, 3),

Answer 1

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.
