Answer 3

Do you know which is the line y = -x ? :)

Answer 4

Do you mean

Answer 5

Is there a certain rule that I need to follow when doing y = -x? For example, I know that when I have y= x, then it means that I need to switch the positions of the x- and y-coordinates? Anything of that sort, in this case?

Answer 6

Yep ! The rule is (x, y) -> (-y, -x)

Answer 7

So when I have y = -x, then I would switch the positions of the coordinate and then find its opposite?

Answer 8

Exactly :)

Answer 9

But if you had (-3 ,2) and you had to find it's reflective point across y = -x, then it would be \((2, -3) \rightarrow (-2, 3)\)
