Official solution

The xx-coordinate of (2,6)(2,6) is 55 less than the xx-coordinate of (7,0)(7,0), and so RR must be translated right 55.

The yy-coordinate of (2,6)(2,6) is 66 more than the yy-coordinate of (7,0)(7,0), and so RR must be translated down 66.

Thus, the translation right 55, down
66 will move R(2,6)R(2,6) to (7,0)(7,0).
