Reflecting Points in Coordinate Geometry

This video tutorial teaches how to reflect points over the x and y axes using a coordinate plane. It covers the basics of the coordinate plane, common plotting mistakes, and the process of reflecting points by changing the sign of coordinates. The tutorial provides examples of reflecting points over the x-axis, y-axis, and to opposite quadrants, summarizing the rules for each type of reflection.

What happens to a point's location if its y-coordinate is changed to negative?

• It stays in the same quadrant.

• It disappears from the plane.

• It moves to a different quadrant.

• It reflects over the y-axis.

When reflecting a point over the x-axis, which coordinate changes?

• Neither coordinate changes.

• The x-coordinate changes.

• The y-coordinate changes.

• Both coordinates change.

If a point is in quadrant 1 and its y-coordinate is made negative, where does it move?

• Quadrant 2

• Quadrant 3

• Quadrant 4

• It stays in quadrant 1

What is the result of changing the x-coordinate of a point to negative?

• The point reflects over the y-axis.

• The point moves to the same quadrant.

• The point disappears.

• The point reflects over the x-axis.

How do you reflect a point to the opposite quadrant?

• Change the y-coordinate to negative.

• Change the x-coordinate to negative.

• Change both coordinates to negative.

• Change neither coordinate.

What happens if both coordinates of a point are made negative?

• The point reflects over the x-axis.

• The point reflects over the y-axis.

• The point moves to the opposite quadrant.

• The point stays in the same quadrant.

Which coordinate remains unchanged when reflecting over the y-axis?

• The x-coordinate

• The y-coordinate

• Neither coordinate

• Both coordinates

To reflect a point over the x-axis, what should you do?

• Change neither coordinate.

• Change both coordinates to negative.

• Change the y-coordinate to negative.

• Change the x-coordinate to negative.

What is the rule for reflecting a point over the y-axis?

• Change neither coordinate.

• Change the y-coordinate to negative.

• Change the x-coordinate to negative.

• Change both coordinates to negative.

What is the effect of taking the opposite of both coordinates of a point?

• The point reflects over the x-axis.

• The point reflects over the y-axis.

• The point moves to the opposite quadrant.

• The point stays in the same quadrant.
