The figure shows two similar triangles on a coordinate grid: A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A triangle ABC is shown with vertex A on ordered pair 1, 2, vertex B on ordered pair 0, 0 and vertex C on ordered pair 3, negative 1. A triangle A prime B prime C prime is also shown with vertex A prime on ordered pair negative 2, 4, vertex B prime on ordered pair 0, 0 and vertex C prime on ordered pair negative 6, negative 2. Which set of transformations have been performed on triangle ABC to form triangle A'B'C'? Dilation by a scale factor of 2 followed by reflection about the x-axis Dilation by a scale factor of 4 followed by reflection about the x-axis Dilation by a scale factor of 2 followed by reflection about the y-axis Dilation by a scale factor of 4 followed by reflection about the y-axis
