The point $P(a, b)$ undergoes the transformations: (i) Reflection about $y = x$; (ii) Translation by 2 units along the positive $x$-axis; (iii) Reflection about $x = 0$. The final image of $P$ is:
Step-by-Step Solution
Key Concept: Step by step: (i) $(a, b) \to (b, a)$; (ii) $(b, a) \to (b + 2, a)$; (iii) reflection in $x = 0$: $(b + 2, a) \to (-(b + 2), a)$.
