Let a be a position vector whose tip is the point (2, -3). If AB = a, where coordinates of A are (-4,5), then the coordinates of B are:

Let $\displaystyle \overrightarrow{\mathrm{a}}$ be a position vector whose tip is the point $\displaystyle (2, -3)$. If $\displaystyle \overrightarrow{\mathrm{AB}}=\overrightarrow{\mathrm{a}}$, where coordinates of A are $\displaystyle (-4,5)$, then the coordinates of B are :
