1. A point A(7,2) is rotated counterclockwise about the origin by 90' and its image is then translated down 2 units. If the final point is labeled as A" then which of the following would be the length of AA"?

please answer this ASAP!! answer honestly to get the points

After you rotate it counterclockwise around the origin by 90 degrees, the point would be (-2,7). Since you translate it down by 2, it would then be (-2,5). The points (-2,5) and the original point (7,2) would form the hypotenuse of a right triangle and you can use the Pythagorean Theorem to find the length of the hypotenuse. The length is 9 units, the height is 3 units.
