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 is negated while the y-coordinate remains the same.
Therefore, the x-coordinate of the reflected point is -(-2) which is equal to 2, and the y-coordinate remains -9.
Thus, the coordinates of the reflected point are (2, -9).
