Question

e is the image of the point e after a reflection.
e(5, 8) → e(5, -8)
over which axis was point e reflected?
x-axis
y-axis

Explanation:

A reflection over the x-axis changes the sign of the y-coordinate of a point, while keeping the x-coordinate the same. For point $E(5, 8)$, its image $E'(5, -8)$ has the same x-coordinate and a negated y-coordinate, which matches the rule for x-axis reflection.

Answer:

x-axis
