SOLUTION
The 270 degree counterclockwise degree rotation about a point is given by the rule
[tex]A(x,y)\Rightarrow A^1(y,-x)[/tex]
From the image above,
The point will be converted by using the rule above
[tex]\begin{gathered} D=(7,4)\Rightarrow D^1(4,-7) \\ E=(6,1)\Rightarrow E^1(1,-6) \\ C=(5,6)\Rightarrow C^1(6,-5) \\ B=(3,3)\Rightarrow B^1(3,-3) \end{gathered}[/tex]
Hence, the image wil be in the fourth quardract are given below.
