The answer is #3: 7x - y = 6.

The condition implies that the mirror m: 2x - y = 1 (slope 2) is an angle bisector of the angle between the line AB: y = x (slope 1) and its image - the line A'B': y = kx + n (coefficients k and n to be determined), or
∡(AB, m) = ∡(m, A'B') /in that order - both angles to be measured counterclockwise!/
Now using the slopes
