Use the image to answer the question. The point (−2, −9) is reflected across the y -axis. What are the coordinates of the reflected point? Responses (2, −9) (2, −9) - no response given (2, 9) (2, 9) - no response given (−9, −2) (−9, −2) - no response given (−2, 9)
The point (−2, −9) is reflected across the y-axis, which means the x-coordinate changes sign while the y-coordinate remains the same. Therefore, the coordinates of the reflected point are (2, -9).
When a point is reflected across the y-axis, its x-coordinate changes sign while the y-coordinate remains the same.
Given that the original point is (-2, -9), reflecting it across the y-axis will result in the x-coordinate changing sign to become positive, while the y-coordinate remains the same. Therefore, the coordinates of the reflected point are (2, -9).
To determine the reflected coordinates of a point across the y-axis, we need to change the sign of the x-coordinate and keep the y-coordinate the same.
Given the point (-2, -9), we will reflect it across the y-axis.
1. Take the x-coordinate of the original point (-2) and change its sign to positive (+2).
2. Keep the y-coordinate the same (-9).
Therefore, the coordinates of the reflected point are (2, -9).
