Here's the solution:
1) The equation $$y = -3x$$ represents a straight line passing through the origin (0,0). As x increases, y decreases because of the negative coefficient. This matches graph Г.
2) The equation $$y = \frac{3}{x}$$ represents a hyperbola. As x approaches zero, y approaches infinity. This matches graph В.
3) The equation $$y = 3$$ represents a horizontal line passing through the point (0,3). This matches graph А.
4) The equation $$y = -x + 3$$ represents a straight line with a negative slope, meaning as x increases, y decreases, and the line intersects the y-axis at 3. This matches graph Б.
So, the correct matches are:
* 1) - Г
* 2) - В
* 3) - А
* 4) - Б
