What is the rule for reflecting in the x=c line

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).

Step-by-step explanation:

There is no rule about x=C..

try soting them out first

step-by-step explanation:

y/x of point b= y/x of point a
