You have not stated the direction of rotation, the mathematical assumption therefore is anti-clockwise.

(-2, -5)

If it goes clockwise it will go to:

(2,5)

Think about it. If you rotate 90 degrees, then what was on the X axis is now on the Y axis and what was on the Y axis is now on the negative X axis. So, -5, 2 rotates to -2, -5

(-2,-5). Just draw the picture and you will see it immediately.
