Question

If the image of the house is reflected across the x
-axis, what will the coordinates of A′
be? 

Answer 1

To find the coordinates of point A' after reflecting point A across the x-axis, you simply need to change the sign of the y-coordinate while keeping the x-coordinate the same.

If the original coordinates of point A are (x, y), then the coordinates of point A' after the reflection across the x-axis will be (x, -y).

If you have the specific coordinates of point A, please provide them, and I can help you calculate the coordinates of A'.
