Transformations and Reflections in Algebra

This video tutorial covers geometric transformations, including translations, reflections, and rotations. It provides detailed explanations and examples for each type of transformation, demonstrating how to perform them on a coordinate plane. The video also includes a brief promotion of an algebra course available on Udemy.

What happens to the x-coordinate of a point when a figure is translated 5 units to the right?

• It remains the same.

• It increases by 5.

• It decreases by 10.

• It decreases by 5.

When reflecting a point over the x-axis, what happens to its y-coordinate?

• It is multiplied by 2.

• It becomes zero.

• It remains the same.

• It is multiplied by -1.

If a point (x, y) is reflected over the y-axis, what will be the new coordinates?

• (x, -y)

• (-x, y)

• (-x, -y)

• (y, x)

What is the result of rotating a point 90 degrees clockwise about the origin?

• (-y, x)

• (-x, -y)

• (y, -x)

• (x, y)

How does a 180-degree rotation affect the coordinates of a point (x, y)?

• (y, -x)

• (-y, x)

• (-x, -y)

• (x, y)

What is the effect of a 90-degree counterclockwise rotation on a point (x, y)?

• (x, y)

• (y, -x)

• (-y, x)

• (-x, -y)

In a practical example, if a point is at (2, 1) and is rotated 180 degrees, where will it be?

• (-1, 2)

• (-2, -1)

• (2, -1)

• (1, -2)
