reflections across the X or Y axis quick check answers

Answer 1

When reflecting a point across the X-axis, the y-coordinate changes sign while the x-coordinate remains the same.

When reflecting a point across the Y-axis, the x-coordinate changes sign while the y-coordinate remains the same.

Here are the quick check answers for a few points:

1. Reflecting the point (3, 4) across the X-axis results in (-3, -4).
2. Reflecting the point (-2, 5) across the Y-axis results in (2, 5).
3. Reflecting the point (0, 0) across the X-axis results in (0, 0) since reflecting across the X-axis does not change the x-coordinate.
4. Reflecting the point (7, -1) across the Y-axis results in (-7, -1).
