v On a coordinate plane, triangle A has points (negative 2, 0), (negative 6, 0), (negative 4, 4). Triangle A prime has points (1, 0), (3, 0), (2, negative 2). Which describes the sequence of transformations used to obtain the image (triangle A’) from the pre-image (triangle A)? dilation by a scale factor of 2, then rotation of 180° about the origin dilation by a scale factor of 2, then a reflection over the x-axis dilation by a scale factor of 1/2, then a rotation of 180° about the origin dilation by a scale factor of 1/2. then a reflection over the x-axis
