Examine the rotation. Which best describes point D?
(-1, 2)✔ (1, 2)(2, -1)(2, 1)
(-7, -1)(-1, -7)(1, -7)✔ (7, -1)
After a rotation of 90° about the origin, the coordinates of the vertices of the image of a triangle are A'(6, 3), B'(–2, 1), and C'(1, 7). What are the coordinates of the vertices of the pre-image?
(-1, 2)✔ (1, 2)(2, -1)(2, 1)
