The rule for a rotation by -270° about the origin, every point (x,y) on this figure maps onto the point ( - y, x ). So, the coordinates of the points are:


\begin{gathered} J(3,3)\rightarrow J^(\prime)(-3,3) \\ K(5,-5)\rightarrow K^(\prime)(5,5) \\ L(-3,-7)\rightarrow L^(\prime)(7,-3) \\ M(3,-3)\rightarrow M^(\prime)(3,3) \end{gathered}

And the new image is:
