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-coordinate of a point when it is reflected across the Y-axis?

• It becomes zero.

• It remains unchanged.

• It becomes negative.

• It becomes positive.

If a point (5, 3) is reflected over the Y-axis, what will be the new coordinates?

• (-5, 3)

• (-5, -3)

• (5, 3)

• (5, -3)

When reflecting a point over the Y-axis, which coordinate remains unchanged?

• X-coordinate

• Y-coordinate

• Both coordinates

• Neither coordinate

What is the visual confirmation of a point being reflected over the Y-axis?

• The point disappears.

• The point moves to a different quadrant.

• The point's X-coordinate changes sign.

• The point's Y-coordinate changes sign.

In the context of reflection over the Y-axis, what does it mean for a point to be in the 'same position'?

• The point is in the same quadrant.

• The point has the same coordinates.

• The point has the same Y-coordinate.

• The point has the same X-coordinate.
