Solution
We have to find the reflection of (3, 5) along x-axis and y-axis.
Reflection of any pointP(a , b) along x-axis is( a, b)
So reflection of (3, 5) along x-axis is( -3 , -5 )
Similarly, reflection of any point P(a,b) along y-axis is (-a , b)
So, reflection of (3, 5) along y-axis is (- 3, 5) .
