ANSWER
(0,2)
EXPLANATION
The mapping point A has coordinate (0,2).
We want to find the coordinates of this point after a rotation of -90° about the origin.
In other words, we want to find the image of this point after a rotation of 90° anticlockwise.
The rule is
[tex](x,y) \to( - y,x)[/tex]
This implies that
[tex](2,0) \to(0,2)[/tex]
