Given a triangle WXY with coordinates
[tex]\begin{gathered} W(1,6),X(3,1),Y(1,1) \\ \end{gathered}[/tex]With the image of the transformation W'X'Y' coordinates as
[tex]W^{\prime}(-6,1),X^{\prime}(-1,3),Y(-1,1)[/tex]The transformation rule is
[tex](x,y)\Rightarrow(-y,x)[/tex]From the transformation rule above, it is observed that the triangle has been rotated 90° counter-clockwise about the origin
The correct option is D
