\(\left\{ \begin{array}{l}{V_{\left( {I; - 2} \right)}}\\I\left( {3; - 1} \right)\\M\left( {4;5} \right)\end{array} \right.\)

Qua\({V_{\left( {I; - 2} \right)}}\) biến \(M\) thành \(M'\)

\(\begin{array}{l} \Rightarrow \overrightarrow {IM'}  = k\overrightarrow {IM}  \Leftrightarrow \left( {x - 3;y + 1} \right) =  - 2\left( {1;6} \right)\\ \Leftrightarrow \left\{ \begin{array}{l}x = 1\\y =  - 13\end{array} \right. \Rightarrow M'\left( {1; - 13} \right).\end{array}\)
