Question

If points Q and reflections of point P (−3, 4) in X and Y axes respectively, what is QR?

Open in App

Solution

We have to find the reflection of (−3, 4) along x-axis and y-axis.

Reflection of any pointalong x-axis is

So reflection of (−3, 4) along x-axis is

Similarly, reflection of any pointalong y-axis is

So, reflection of (−3, 4) along y-axis is

Therefore,
