Der Abbildung kannst du folgende Vektorgleichung entnehmen:

$\overrightarrow{OD}+\overrightarrow{AB}=\overrightarrow{OC}\backslash overrightarrow\{OD\}+\backslash overrightarrow\{AB\}=\backslash overrightarrow\{OC\}$

$\left(\begin{array}{c}-1\\ 6\end{array}\right)+\left(\begin{array}{c}2\\ 7\end{array}\right)=\left(\begin{array}{c}1\\ 13\end{array}\right)\backslash begin\{pmatrix\}-1\backslash \backslash 6\backslash end\{pmatrix\}+\backslash begin\{pmatrix\}2\backslash \backslash 7\backslash end\{pmatrix\}=\backslash begin\{pmatrix\}1\backslash \backslash 13\backslash end\{pmatrix\}$

Demnach hat der Punkt $CC$ die Koordinaten $C(1\mathrm{\mid }13)C(1|13)$.
