The point (–3, –4) is reflected across the x-axis.

What quadrant is the reflected point located?
A. Quadrant I
B. Quadrant II
C. Quadrant III
D. Quadrant IV

The point (–3, –4) is located in Quadrant III. However, when a point is reflected across the x-axis, the x-coordinate remains the same and the sign of the y-coordinate is reversed. Therefore, the reflected point will be (–3, 4), which is located in Quadrant I. So, the correct answer is:

A. Quadrant I
