what are the coordinates of a point p(x, y) reflected across the y-axis? across the x-axis?

there's no i'm so confused.

answer:

step-by-step explanation:

reflect over the 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).

the answer is a if my teacher taught me correct
