    in order to get the symmetric point with respect to the origin you have to apply this transformation: \[\begin{gathered} x \to - x \hfill \\ y \to - y \hfill \\ \end{gathered} \]

    So it would be (-2, -9) ??

    correct! for the symmetric point with respect to \(x-\)axis, we have: \[\begin{gathered} x \to x \hfill \\ y \to - y \hfill \\ \end{gathered} \]

    finally for symmetric point with respect to \(y-\)axis, we have: \[\begin{gathered} x \to - x \hfill \\ y \to y \hfill \\ \end{gathered} \]

    we have three answers: symmetric with respect to the origin: (-2,-9) symmetric with respect to the x-axis: (2,-9) symmetric with respect to y-axis: (-2,9)
