Triangle QNP was dilated by a scale factor of One-third about point P. It was then transformed in another way to produce Triangle Q prime N prime P prime. On a coordinate plane, triangle Q N P has points (negative 1, 0), (negative 7, 9), (negative 1, 9). Triangle Q prime N prime P prime has points (6, 1), (9, 3), (9, 1). Which identifies the transformation that occurred after the dilation? a 90 degrees clockwise rotation about the origin a 180 degrees clockwise rotation about the origin a reflection across the x-axis a reflection across the y-axis
