How to reflect a line over the origin

The video tutorial explains how to reflect points over the origin, which involves reflecting over both the X and Y axes. It begins with an introduction to the concept of the origin and its significance in coordinate geometry. The tutorial then outlines the rules for reflecting points over the origin, followed by a practical example using points A and B. The importance of labeling and graphing the reflected points is emphasized to avoid errors. Finally, the video provides a visualization of how points are reflected over the axes, ensuring a clear understanding of the process.

What is the origin in a coordinate system?

• The point where the Y axis meets the Z axis

• The point where the X axis meets the Z axis

• The point where the X and Y axes intersect

• The point where the X, Y, and Z axes intersect

Reflecting a point over the origin involves:

• Reflecting over the Z axis

• Reflecting over the X axis only

• Reflecting over both the X and Y axes

• Reflecting over the Y axis only

If a point A is at (-4, 1), what is its reflection over the origin?

• (4, -1)

• (-1, 4)

• (-4, -1)

• (4, 1)

Why is it important to label transformed points on a graph?

• To increase the complexity of the graph

• To make the graph easier to erase

• To make the graph look colorful

• To avoid confusion and ensure accuracy

What should you do if you find it difficult to visualize the reflection process?

• Use a calculator

• Ignore the rules and guess

• Follow the rules for reflection

• Ask someone else to do it
