Question

What will be the coordinates of a point P(a,b) when it is reflected on the line y=0?

Answer 1

Answer:

the y-axis is the point (-x,y). 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).
