Final answer:
After reflecting point B at (11, -5) over the x-axis, its image B' will have coordinates (11, 5). The correct answer is A) (11,5).
Step-by-step explanation:
The question involves the reflection of a point over the x-axis in coordinate geometry. When a point (x, y) is reflected over the x-axis, the x-coordinate remains the same, but the y-coordinate changes sign.
Therefore, after the reflection of point B located at (11, -5), the new coordinates will be (11, 5), since only the sign of the y-coordinate changes.
To find the image of B after a reflection over the x-axis, we need to change the sign of the y-coordinate of B. Since the original y-coordinate is -5, when we reflect it over the x-axis, the y-coordinate becomes positive, resulting in the image B' having the coordinates (11, 5).
