Answer:
(0, 9) - remains the same
Step-by-step explanation:
The reflection over the y-axis is a transformation that flips the coordinates of a point across the y-axis.
Given the point (0, 9), the reflection over the y-axis would result in a new point with the x-coordinate being negative and the y-coordinate unchanged. Therefore, after the reflection over the y-axis, the image of (0, 9) would be (-0, 9), which can also be written as (0, 9). In other words, the point remains the same after the reflection over the y-axis.
