To determine which point is NOT on the line given by the equation $$ y = 2x + 3 $$, we will substitute the $$ x $$-coordinate of each point into the equation and see if the resulting $$ y $$-value matches the $$ y $$-coordinate of the point.

1. For the point $$ (-1, 1) $$:
   $$
   y = 2(-1) + 3 = -2 + 3 = 1
   $$
   The point $$ (-1, 1) $$ is on the line.

2. For the point $$ (0, 5) $$:
   $$
   y = 2(0) + 3 = 0 + 3 = 3
   $$
   The point $$ (0, 5) $$ is NOT on the line.

3. For the point $$ (2, 7) $$:
   $$
   y = 2(2) + 3 = 4 + 3 = 7
   $$
   The point $$ (2, 7) $$ is on the line.

4. For the point $$ (3, 9) $$:
   $$
   y = 2(3) + 3 = 6 + 3 = 9
   $$
   The point $$ (3, 9) $$ is on the line.

Thus, the point that is NOT on the line $$ y = 2x + 3 $$ is $$ (0, 5) $$.
The point $$ (0, 5) $$ is NOT on the line $$ y = 2x + 3 $$.
