Draw the dilation image a'b'c'd' of the trapezoid abcd with the center of the dilation at the origin and the scale factor -2.

The coordinates of the trapezoid ABCD

A(-4,-1) , B(-1,-1) , C(0,-5) and (-5,-5)

The dilation at the origin and the scale factor -2.

So, the rule will be ⇒ (x,y)→(-2x,-2y)
So, A(-4,-1) ⇒⇒⇒ A'(8,2)
      B(-1,-1) ⇒⇒⇒ B(2,2)
      C(0,-5) ⇒⇒⇒ C'(0,10)
      D(-5,-5) ⇒⇒⇒ D'(10,10)

See the attached figure .
