A translation of 2 units down takes S to the point (1, -1). Then a counterclockwise rotation about the origin takes S to the point (-1, -1) where we have S' .
I believe it is <em>'A translation 2 units down followed by a 90-degree counterclockwise rotation about the origin' </em>because if we try to do a 90 degree counterclockwise it would be 2 units off, therefore if we went down 2 units and went counterclockwise it would line it.
