What is the rule for the reflection? ry=x(x, y) → (–y, –x) ry=–x(x, y) → (–y, –x) ry=x(x, y) → (y, x) ry=–x(x, y) → (y, x)

We have to identify the rules of reflection.

Firstly, the rule for reflecting a point about the line y=x is:

While reflecting about the line y=x, we get the reflected points by swapping the coordinates.

So, Option 3 is correct.

Now, the rule for reflecting a point about the line y= -x is:

While reflecting about the line y= -x, we get the reflected points by multiplying '-1'  with the swapped coordinates.

So, Option 2 is correct.

C. r y = x (x, y) → (y, x).

Step-by-step explanation:

It appears that the triangle was reflected over the line y = x. According to the Coordinate Rules of Reflection, (x, y) would change and become (y, x). That resembles option C. r y = x (x, y) --> (y, x).

Hope this helps!
