Given the Pre-Image (the original figure) JKL, and the Image (the figure after the transformation) J'K'L', you can identify that the vertices of JKL are:


\begin{gathered} J(-2,-4) \\ K(-2,-2) \\ L(1,-2) \end{gathered}

And the vertices of the Image are:


\begin{gathered} J^(\prime)(4,2) \\ K^(\prime)(2,2) \\ L^(\prime)(-1,2) \end{gathered}

You can notice that the signs of the coordinates of the Image are obtained by multiplying the original coordinates by -1.

By definition, the rule for a Rotation of 180 degrees centered at the Origin is:


(x,y)\rightarrow(-x,-y)

Hence, the answer is:


(x,y)\rightarrow(-x,-y)
