Question

Find the coordinates of the vertices of each figure after the given transformation
Reflection over the y-axis A (5,-7)

Answer 1

To find the coordinates of the vertex after reflecting point A(5, -7) over the y-axis, we need to change the sign of the x-coordinate while keeping the y-coordinate the same.

1. The original point A is (5, -7).
2. After reflection over the y-axis, the x-coordinate becomes -5, and the y-coordinate remains -7.

Thus, the coordinates of the reflected point A' are:

\[
A' = (-5, -7)
\]

So, the coordinates of point A after the reflection over the y-axis are (-5, -7).
