Answer:
What is the rule for a reflection across the line y =- X?
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).
Explanation:
There is no rule about x=C..
