Reflections across the y-axis
THE point (-2, -9 is reflected across the y axis whater are the are the cordibnate of the reflected points
1 answer
When a point is reflected across the y-axis, the x-coordinate changes sign. In this case, the original point is (-2, -9), and reflecting it across the y-axis gives (2, -9). Thus, the coordinates of the reflected point are (2, -9).
