How to reflect a point over the y axis

The video tutorial explains how to reflect a point across the Y axis. It begins by introducing the concept of reflection and the changes in coordinates that occur when a point is reflected. The tutorial provides an example using the point (5, 3), showing how it becomes (-5, 3) after reflection. The process of plotting the reflected point is demonstrated, emphasizing that the X coordinate changes sign while the Y coordinate remains the same. The tutorial concludes by summarizing the reflection process and its effects on coordinates.

What happens to the X coordinates of a point when it is reflected over the Y axis?

If a point has coordinates (5, 3), what will its coordinates be after reflecting over the Y axis?

Describe the relationship between the original point and its reflection over the Y axis.

How does the reflection over the Y axis affect the position of a point in relation to the axis?

Explain why the X coordinate becomes negative when reflecting a point over the Y axis.
