This kind of transformation results in a similar figure.
So the triangle A'B'C' will be similar to triangle ABC: which means that all the angles are preserved (thy are congruent).
Being the angles congruent the slope of B'C' will be the same angle of BC.
Since, the slope of AB is - 1, the other two sopes are one 0 and the other undefined (∞). The horizontal side has slope 0 and the vertical side has slope ∞.
Since you did not attache any figure I do not know whether B'C' is the horizontal or the vertical side.
The answer is that the slope of B'C' is zero if it is the horizontal side, and the slope is ∞ if B'C' is the vertical side.
