Final answer:
The coordinates of vertex e after Δpqr is reflected over the x-axis would be (x, -y), where (x, y) are the original coordinates of the corresponding vertex before reflection.
Step-by-step explanation:
To find the coordinates of vertex e after Δpqr is reflected over the x-axis, we need to look at the coordinates of the corresponding vertex before the reflection. If the original coordinates of a point are (x, y), then after reflection over the x-axis, the new coordinates become (x, -y) because the x-coordinate remains the same while the y-coordinate is negated.
To provide a specific answer, we need the original coordinates of vertex e before the reflection. However, I can explain that if for example, the original coordinates were (3, 4), after reflecting over the x-axis, the new coordinates for vertex e would be (3, -4).
