Answer:
G(9, -5)
Explanation:
Point G is not shown in the figure, but I assume point G is on the bottom side of the square, directly below point F.
We are told each side of the square is 8 units long.
Starting at point E, to get to point G, go 8 units right and 8 units down.
Start at E(1, 3).
Then go 8 units right to point F(9, 3).
Now go 8 units down to point G(9, -5).
