To determine the quadrant of the reflected point across the x- and y-axes, we start with the original point \((-16, 11)\).
-
Reflecting across the x-axis:
- The x-coordinate stays the same, while the y-coordinate changes sign.
- This gives us the point \((-16, -11)\).
-
Reflecting across the y-axis:
- The y-coordinate stays the same, while the x-coordinate changes sign.
- This gives us the point \((16, -11)\).
Now, let's determine the quadrant of the final reflected point \((16, -11)\):
- The x-coordinate \(16\) is positive.
- The y-coordinate \(-11\) is negative.
This means the point \((16, -11)\) is located in Quadrant IV, where x is positive and y is negative.
So the answer is:
Quadrant IV.
