Question

If P= (-1,5), Find:
Rx=1 (P)
([?],[])​

Answer 1

The reflection will be on the point (3, 5).

Explanation:

For a given point (x, y) reflection along the line x = k, the co-ordinates will be:

`$ R_(x = k) (x, y) = (2k - x, y) $`.

Here, we have (x, y) = (-1, 5)

Reflection across the line x = 1, we have:

`$ R_(x = 1) (-1, 5) = (2(1) - (-1), 5) $`

= (3, 5)

Hence, the reflection of the point (-1, 5) would be the point (3, 5).
