Which point is the image of (2, -7) after reflecting across the y-axis?

Explanation:
Reflecting across the y-axis changes the sign of the x-coordinate while leaving the y-coordinate the same. So the image of (2, -7) becomes (-2, -7). The y value stays -7, and the x value flips from 2 to -2. The other coordinates would imply changing the y value or leaving x unchanged, which isn’t what happens with a reflection across the y-axis.
