Triangle JKL is transformed using the rule . Point K of the pre-image is at (4, 7). What are the coordinates of point K" on the final image? (–7, –4) (–4, –7) (4, –7) (4, 7)

Option C.

Step-by-step explanation:

Consider the complete question is "Triangle JKL is transformed using the rule . Point K of the pre-image is at (4, 7). What are the coordinates of point K'' on the final image?".

According to , we get

According to , we get

The rule means first reflection and then rotation.

We need to find the image of K(4,7).

After reflection, we get

After rotation, we get

Therefore, the correct option is C.

answer: 7
