Assuming:
- R270 is a clockwise rotation about the origin
- T3,2 is a translation by 3 in the x-coordinate and 2 in the y
Then for any point (x,y), we'll get:
R270 T3,2
(x,y) -------> (-y,x) -------> (-y+3, x+2)
In your case, (x,y) = (6,5). Plug the values into the above transformations to get the image point.
