How to reflect a trapezoid over the y=x axis

The video tutorial covers graphing on a coordinate grid, including plotting and labeling points. It explains how to reflect points over the Y-axis, detailing the transformation process and the rule that changes the sign of the X-coordinate. The tutorial emphasizes the importance of accuracy in plotting and reflecting points.

What is the importance of labeling points on a coordinate grid?

• It is required for calculating distances.

• It makes the graph look colorful.

• It is a rule in mathematics.

• It helps in identifying the points easily.

Which of the following points is correctly labeled based on the given coordinates: (0, -3)?

• Point G

• Point F

• Point D

• Point E

What changes when a point is reflected over the Y-axis?

• The Y-coordinate changes sign.

• Neither coordinate changes sign.

• The X-coordinate changes sign.

• Both coordinates change sign.

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

• (3, 3)

• (-3, -3)

• (3, -3)

• (-3, 3)

What is the new position of point G after reflection over the Y-axis?

• (-4, 3)

• (4, 3)

• (-4, -3)

• (4, -3)
