The rule for a 90° rotation about the origin is:
[tex](x,y)\rightarrow(-y,x)[/tex]
then, if we select one of the points of the figure, A(-2,1), and apply the transformation,
[tex]A(-2,1)\rightarrow A^{\prime}(-1,-2)[/tex]
do the same for the other three points,
[tex]\begin{gathered} B(3,3)\rightarrow B^{\prime}(-3,3) \\ C(4,0)\rightarrow C^{\prime}(0,4) \end{gathered}[/tex]
select the graph with all three points.
Answer:
The correct answer is option 4.
