What set of transformations is performed on triangle RST to form triangle R’S’T’?

A 90-degree counterclockwise rotation about the origin followed by a translation 2 units left
A 270-degree counterclockwise rotation about the origin followed by a translation 2 units to the right
A translation 2 units down followed by a 90-degree counterclockwise rotation about the origin
A translation 2 units down followed by a 270-degree counterclockwise rotation about the origin

What set of transformations is performed on triangle RST to form triangle RST A 90degree counterclockwise rotation about the origin followed by a translation 2 class=

Answer:

The last option is correct

Step-by-step explanation:

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 'A translation 2 units down followed by a 90-degree counterclockwise rotation about the origin' 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.
