Reflections on the Coordinate Plane

If the coordinates of a point are (x, y), what are the coordinates after reflecting over the x-axis?

• (x, y)

• (-x, y)

• (x, -y)

• (-x, -y)

If point C is at (1, -3), what are the coordinates of C' after reflecting over the x-axis?

• (1, 3)

• (-1, -3)

• (1, -1)

• (3, 1)

What is the effect of reflecting a point on the coordinate plane?

• It creates a mirror image of the point across the specified axis.

• It moves the point to a random location on the plane.

• It changes the color of the point on the plane.

• It rotates the point around the origin.

If the coordinates of a point are (x, y), what are the coordinates after reflecting over the y-axis?

• (x, -y)

• (-x, y)

• (y, x)

• (-y, -x)

If point B is at (-5, -2), what are the coordinates of B' after reflecting over the x-axis?

• (-5, 2)

• (5, -2)

• (-5, -2)

• (5, 2)

What happens to the coordinates of a point when it is reflected over the y-axis?

• The x-coordinate changes sign, while the y-coordinate remains the same.

• The y-coordinate changes sign, while the x-coordinate remains the same.

• Both the x-coordinate and y-coordinate change signs.

• The coordinates remain unchanged.

Reflect the point (-4, 1) over the x-axis. What are the new coordinates?

• (-4, -1)

• (4, 1)

• (-4, 1)

• (4, -1)

What is the definition of reflection in geometry?

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

• Reflection is a process of measuring angles in a triangle.

• Reflection is a method of calculating the area of a circle.

• Reflection is a technique used to rotate a figure around a point.

What is the result of reflecting the point (0, 5) over the y-axis?

• (0, 5) - The point remains unchanged.

• (-0, 5) - The point moves to the left.

• (0, -5) - The point moves down.

• (5, 0) - The point moves to the right.

What is the relationship between a pre-image and its image after reflection?

• They are congruent polygons.

• They are similar but not congruent.

• They are identical in size but not in shape.

• They are completely different shapes.
