The parallelogram on the left was dilated by a scale factor of 2 about point P. It was then transformed in another way to produce the parallelogram on the right. On a coordinate plane, parallelogram P has points (negative 4, 0), (negative 2, 0), (negative 3, negative 3), (negative 5, negative 3). Parallelogram P prime has points (3, 0), (7, 0), (5, negative 6), (1, negative 6).
Which identifies the transformation that occurred after the dilation?
a translation of 9 units to the right
a translation of 3 units down
a reflection across the x-axis
a reflection across the y-axis
