Answer: The new location of point A is (-2, 3).
Step-by-step explanation: Given that a point A is reflected over the y-axis and its original location was (2,3).
We are to find the new location of point A.
We know that
if a point (x, y) is reflected across the y-axis, the sign before the x co-ordinate changes.
That is,
(x, y) ⇒ (-x, y).
Therefore, for point (2, 3), the new location is given by
(2, 3) ⇒ (-2, 3).
Thus, the new location of point A is (-2, 3).
