Final answer:
The point (6,7) after a 90-degree clockwise rotation ends up in Quadrant IV, and remains in Quadrant IV after a reflection over the x-axis.
Step-by-step explanation:
The question involves performing two transformations on a point in the coordinate system. Initially, the point (6,7) is located in Quadrant I. If we rotate this point 90 degrees clockwise, it moves to Quadrant IV, since a clockwise rotation from Quadrant I would make a right turn to land in the quadrant where the x-values are positive, and y-values are negative. Next, reflecting this new point over the x-axis involves changing the sign of the y-coordinate, resulting in a point that is still in Quadrant IV, as it would then have both positive x and y coordinates.
