Learn how to reflect over the y=x line ex 3

The video tutorial explains how to reflect a figure over the y=x line. It begins by plotting the pre-image points and understanding the properties of the y=x line. The tutorial then demonstrates the reflection process by swapping the x and y coordinates of the points. Finally, it plots the new image points and shows that the reflected figure is symmetrical to the original across the y=x line.

What is the primary characteristic of the y = x line in terms of coordinates?

• y is always greater than x

• x is always greater than y

• x and y coordinates are unrelated

• x and y coordinates are equal

What is the first step in reflecting a figure over the y = x line?

• Draw the x and y axes

• Calculate the distance from the origin

• Plot the y = x line

• Swap the x and y coordinates

How do you determine the new coordinates after reflecting over the y = x line?

• Add 1 to both x and y

• Subtract y from x

• Multiply x and y by 2

• Swap the x and y coordinates

What is the new coordinate of point A if its original coordinate is (6, 3) after reflection over the y = x line?

• (0, 0)

• (6, 3)

• (9, 9)

• (3, 6)

What is the final step in completing the reflection of a figure over the y = x line?

• Recalculate the original coordinates

• Connect the new image points

• Draw a new y = x line

• Erase the original figure
