Answer:

The coordinates of point A is;

Step-by-step explanation:

Given that the coordinates of the image of point A is;

$A^(\prime)(5,-7)$

And the translation vector is;

which gives the rule;

$A(x,y)\rightarrow A^(\prime)(x+7,y-3)=A^(\prime)(5,-7)_{}$

So, we have;

$\begin{gathered} x+7=5 \\ x=5-7 \\ x=-2 \\ y-3=-7 \\ y=-7+3 \\ y=-4 \end{gathered}$

Therefore, the coordinates of point A is;
