Question

what is the rule for a reflection over the x - axis? (x, y) --> (y, -x) (x, y) --> (-y, x) (x, y) --> (-x, y) (x, y) --> (x, -y)

Explanation:

In a reflection over the x - axis, the x - coordinate of a point remains the same and the y - coordinate changes its sign.

Answer:

$(x,y)\to(x, - y)$
