Reflecting Points over the x- and y-Axes in a Coordinate Plane

This video tutorial teaches how to reflect points over the x- and y-axes using a coordinate plane. It explains the process of changing the sign of coordinates to reflect points across axes and into opposite quadrants. The tutorial covers common mistakes, such as incorrect plotting, and provides a summary of reflection rules.

What is a common mistake when plotting points on a coordinate plane?

• Going up and then over

• Using positive coordinates

• Using negative coordinates

• Going over and then up

How do you reflect a point over the x-axis?

• Change the x-coordinate to negative

• Change the y-coordinate to negative

• Keep both coordinates the same

• Change both coordinates to negative

If a point is in quadrant II and you change both coordinates to their opposites, where will it move?

• Quadrant I

• Quadrant III

• Quadrant II

• Quadrant IV

What happens when you reflect a point over the y-axis?

• Both coordinates change sign

• Neither coordinate changes sign

• The y-coordinate changes sign

• The x-coordinate changes sign

To reflect a point to the opposite quadrant, what should you do?

• Change the x-coordinate to positive

• Change the y-coordinate to positive

• Keep both coordinates the same

• Change both coordinates to their opposites
