Reflection across the y-axis

Reflection across the x-axis

Answer explanation

The image appears to be flipped from the preimage, which indicates a reflection.

The figure would need to be flipped/reflected across the x-axis to be oriented the way it is. Think of it like a page turned from preimage to image, with the page "attached" at the x-axis.

What axis is the image reflected over?

X-axis

Reflections over the x-axis change the ____-__________.

y-coordinate

Answer explanation

If you compare the points in the visual example, you can see that the x-values are the same but the sign of the y-value was changed.

Therefore, reflecting over the x-axis changes the y-coordinate.
