Answer:
The answer is "[tex]\bold{R(y=x) = (x, y) \to (y, x)}[/tex]"
Explanation:
If A coordinates are = (-2, 1)
so,
The coordinates of A' = (1, -2)
Its values had also obviously been replaced order are:
[tex]= (x, y) \to (y, x)[/tex]
Now that's the product of an overview of y = x. That's why the rule and its name is: [tex]R(y=x) = (x, y) \to (y, x)[/tex].
