Your answer must be listed as a coordinate so use parenthesis.

Answer 1

To reflect the point \( B(5, -9) \) over the x-axis, you keep the x-coordinate the same and change the sign of the y-coordinate.

Thus, the reflection of the point is:

\[ B' = (5, -(-9)) = (5, 9) \]

So the coordinates of \( B' \) are \( (5, 9) \).
