Question

The coordinates of point A on a grid are (−4, 3). Point A is reflected across the y-axis to obtain point B. The coordinates of point B are (___, 3)

Answer 1

(4, 3)

Explanation:

This means the y-axis behaves like a mirror and point B is akin to the virtual image formed by point A.

A line between the two points should form a 90 degrees angle at the point of intersecting with the y-axis. The two points, too, should be equidistant at either end from the y-axis,
