Question

what happens to the coordinates of a point when it is reflected over the x - axis?
a. both coordinates are negated.
b. the y - coordinate is negated.
c. the x - coordinate is negated.
d. the coordinates are swapped.

Explanation:

When a point $(x,y)$ is reflected over the x - axis, the x - value remains the same and the y - value changes its sign. For example, if we have a point $(2,3)$ and reflect it over the x - axis, it becomes $(2, - 3)$.

Answer:

B. The y - coordinate is negated.
