The reflection of (3, 2) across the y-axis is which point?

Explanation:
Reflecting across the y-axis creates a mirror image left to right, so only the x-coordinate changes sign while the y-coordinate stays the same. From (3, 2), the x value goes from 3 to -3 while the y value remains 2, giving (-3, 2). The other options would flip the y-coordinate or leave the point unchanged, which doesn’t match a reflection across the y-axis.
