Reflections on the Coordinate Plane

What happens to the coordinates of a point when it is reflected over both axes?

• The coordinates remain the same (x, y)

• The coordinates change to (x, -y)

• The coordinates change to (-x, y)

• The coordinates change to (-x, -y)

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

• Change the sign of the y-coordinate, resulting in (x, -y).

• Change the sign of the x-coordinate, resulting in (-x, y).

• Leave the coordinates unchanged, resulting in (x, y).

• Swap the coordinates, resulting in (y, x).

What is a reflection in the coordinate plane?

• A transformation that rotates a figure around a point.

• A transformation that flips a figure over a line, creating a mirror image.

• A transformation that enlarges a figure while maintaining its shape.

• A transformation that translates a figure to a different location.
