Question

The figure above the x-axis is the preimage. The figure below the x-axis is the image. Which transformation produced the image?

A.
reflection across the x-axis
В.
reflection about the origin
C.
rotation 90° clockwise about the origin
D.
rotation 90° counterclockwise about the origin
​

Answer 1

B

Explanation:

yes

Answer 2

Option B.

Explanation:

From the picture attached, figure above the x-axis is the pre-image and below the axis is the image.

Let's choose a point B of the image having coordinates (0, 2).

When the point B is transformed, coordinates of the point B' is (0, -2)

And the rule for this transformation will be,

(x, y) → (-x, -y)

This rule shows the reflection of pre-image over the origin.

Option (B). will be the answer.
