The point -2 -9 is reflected across the y axis. What are the coordinates of the reflected point?
When a point is reflected across the y-axis, the x-coordinate changes sign, while the y-coordinate remains the same.
The original coordinates are (-2, -9), so when reflected across the y-axis, the x-coordinate changes sign and becomes positive 2, while the y-coordinate remains -9.
Therefore, the coordinates of the reflected point are (2, -9).
