21. A triangle has vertices (1, 5), (2, 7), and (6, 5). After a reflection and a translation, the
coordinates of the image are (5,-2), (6,-4), and (10,-2). Describe the transformation.
22. Find the image of the point at (4, -7) under the translation along the vector (a, b).
I am not sure about number 22. Â I think that they are asking you to apply the same rules to the point (4, -7), if that is what they mean, the answer is (8,10)
