The table shows the coordinates of the vertices of pentagon ABCDE. Pentagon ABCDE is dilated by a scale factor of $$\frac{7}{3}$$ with the origin as the center of dilation to create pentagon A'B'C'D'E'. If $$(x, y)$$ represents the location of any point on pentagon ABCDE, which ordered pair represents the location of the corresponding point on pentagon A'B'C'D'E'?

J $$\left( \frac{7}{3}x, \frac{7}{3}y \right)$$

F $$\left( \frac{3}{7}x, \frac{3}{7}y \right)$$

G $$\left( x + \frac{7}{3}, y + \frac{7}{3} \right)$$

H $$\left( x + \frac{3}{7}, y + \frac{3}{7} \right)$$
