Answer:
OPTION C: (-5, 4)
Explanation:
We are asked to determine the point of reflection along the line y = x.
When a point, say (a, b) is reflected along y = x, then the x - co ordinate and y - co ordinate change place.
That is, they will be reflected as: (b , a).
This is in line with the reflection of an image in a mirror.
So, here, since the point is: , (4, -5) the reflection would be on (-5, 4).
Hence, OPTION C is the answer.
