The calculated coordinate for S' is D. (1, 1)
How to determine the coordinate for S'?
From the question, we have the following parameters that can be used in our computation:
S = (1, 1)
Also, we have the reflection to be
A reflection across the line y = x
The rule of this reflection is
(x, y) = (y, x)
Using the above as a guide, we have the following:
S' = (1, 1)
Hence, the coordinate for S' is D. (1, 1)
