Which point is the reflection of $(3, -5)$ across the **x-axis**?
A$(-3, -5)$
B$(3, 5)$
C$(-3, 5)$
D$(-5, 3)$
Answer & Solution
Correct answer: B. $(3, 5)$
Reflection across the $x$-axis negates the $y$-coordinate: $(x, y) \to (x, -y)$. So $(3, -5) \to (3, 5)$.
- Trap A reflects across the $y$-axis instead.
- Trap C reflects across the **origin**.
- Trap D swaps coordinates (reflection across $y = x$).
