Question

Reflect point M over the y-axis. Find the coordinates of M

Answer 1

When reflecting a point over the y-axis, the x-coordinate of the reflected point will be the same as the original point, but the sign of the y-coordinate will change.

Therefore, if the original point is M(x, y), the reflected point M' will have coordinates (-x, y).

So, by reflecting point M over the y-axis, the coordinates of M' will be (-x, y).
