How to reflect a triangle over the y=x line

The video tutorial explains how to plot and reflect coordinate points over the Y = X line. It begins with plotting original points, then describes the reflection process both graphically and algebraically. The tutorial demonstrates swapping X and Y coordinates to achieve reflection and concludes with plotting the new reflected points. Students are assigned similar tasks to practice the learned concepts.

What is the first step in plotting the original coordinates?

• Graph the line Y = X

• Swap the X and Y values

• Identify and write down the original coordinates

• Reflect the points over the Y = X line

How do you find the reflection of a point over the line Y = X?

• Swap the X and Y coordinates

• Subtract the Y value from the X value

• Multiply the X and Y values

• Add the X and Y values

What is the new coordinate of point F after reflection?

• (-3, 2)

• (-2, 3)

• (2, -3)

• (3, -2)

Which of the following is the correct reflected coordinate for point G?

• (1, 4)

• (4, 1)

• (-1, -4)

• (-4, -1)

What is the final task assigned to the students?

• Swap the X and Y values of four new points

• Plot the original coordinates again

• Graph the line Y = X

• Reflect four new points over the Y = X line
