Question:
Write the coordinates the reflections of points (3, 5) in X and Y -axes.
Solution:
We have to find the reflection of (3, 5) along x-axis and y-axis.
Reflection of any point $P(a, b)$ along $x$-axis is $(a,-b)$
So reflection of $(3,5)$ along $x$-axis is $(3,-5)$
Similarly, reflection of any point $\mathrm{P}(\mathrm{a}, \mathrm{b})$ along $y$-axis is $(-a, b)$
So, reflection of $(3,5)$ along $y$-axis is $(-3,5)$
