Match the function with the corresponding graph.

Okay, let's analyze the graphs and match them to the given functions.

* Function 1: y = -x This is a straight line with a negative slope. When x increases, y decreases. This matches graph Б.
* Function 2: y = -1 This is a horizontal line at y = -1. In the provided image, none of the graphs clearly show y = -1, so there might be missing graph, or error in the task.
* Function 3: y = x - 1 This is a straight line with a positive slope and a y-intercept of -1. This matches graph A.

So, the matching is:

* A: y = x - 1
* Б: y = -x
* B: y = -1

Answer: A3, Б1, B2
