Question

A shape is reflected over the y-axis then dilated by a scale factor of 0.5. The original coordinates of point A were (3, 4). What are the coordinates of point A after the reflection?

Answer 1

To find the coordinates of point A after it has been reflected over the y-axis, we need to change the x-coordinate of the point from positive to negative, while keeping the y-coordinate the same.

The original coordinates of point A are (3, 4).

After reflecting over the y-axis:
- The x-coordinate changes from 3 to -3.
- The y-coordinate remains 4.

Thus, the coordinates of point A after the reflection are:

\[
(-3, 4)
\]
