How to reflect a point over the x axis

The video tutorial explains how to reflect points over the X and Y axes. It introduces the concept of reflection, provides a formula for reflecting a point over the X axis, and demonstrates this with a practical example. The tutorial also includes a graphical approach to understanding reflection and concludes by encouraging students to practice the concept.

What is the formula for reflecting a point over the X-axis?

• X, -Y

• X, Y

• -X, Y

• -X, -Y

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

• (5, 3)

• (-5, 3)

• (5, -3)

• (-5, -3)

In the example given, what is the original point before reflection?

• (-5, 3)

• (3, -5)

• (5, 3)

• (3, 5)

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

• It becomes positive

• It becomes negative

• It remains the same

• It becomes zero

What is the graphical effect of reflecting a point over the X-axis?

• The point moves to the right

• The point moves to the left

• The point flips horizontally

• The point flips vertically
