Question

what is the rule if you reflect a point over y - axis? * (x,y) changes to (x,-y) (x,y) changes to (-x,-y) (x,y) changes to (-y,x) (x,y) changes to (-x,y) 2 points

Explanation:

When reflecting a point $(x,y)$ over the y - axis, the x - coordinate changes its sign while the y - coordinate remains the same. This is because the y - axis acts as a mirror, and the distance of the point from the y - axis in the x - direction is reversed.

Answer:

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