We need to reflect the point $$ (3,-4) $$ across the line $$ y = 1 $$.

1. For a reflection of a point $$ (x,\, y) $$ about the line $$ y = c $$, the $$ x $$-coordinate remains unchanged, and the $$ y $$-coordinate is given by
   $$
   y' = 2c - y.
   $$
   
2. Here, $$ c = 1 $$ and the original point is $$ (3,-4) $$. Plugging in the values, we have
   $$
   y' = 2(1) - (-4) = 2 + 4 = 6.
   $$

3. Therefore, the reflected point is
   $$
   (3,6).
   $$

Thus, the reflection of the point $$ (3,-4) $$ across the line $$ y = 1 $$ is $$ (3,6) $$.
The reflection of the point (3, -4) across the line $$ y = 1 $$ is (3, 6).
