Answer: C. ry=x(x, y) → (y, x)
Step-by-step explanation:
From the given picture, the coordinates of A = (-2,1), B(3,4) and C(-4,1)
and the coordinates of A' =(1,-2), B'(4,3) and C'(1,-4)
We can see that the x and y coordinates of ΔABC has changed their place in ΔA'B'C'.
Therefore, the rule for the given reflection is in option C.
i.e. ry=x(x, y) → (y, x) .
