Which describes how triangle FGH could be transformed to triangle F prime G prime H prime in two steps? On a coordinate plane, triangle F G H has points (negative 2, 1), (negative 3, 3), (0, 1). Triangle F prime G prime H prime has points (negative 8, negative 4), (negative 12, negative 12), (0, negative 4).

Which identifies the transformation that occurred after the dilation?

a dilation by a scale factor of 3 and then a 180 degrees rotation about the origin
a dilation by a scale factor of 4 and then a reflection across the x-axis
a dilation by a scale factor of 4 and then a 180 degrees rotation about the origin
