Final answer:
The point (9, -10) would be located in Quadrant 4.
Step-by-step explanation:
The point (9, -10) would be located in Quadrant 4.
In a Cartesian coordinate system, Quadrant 4 is the bottom-right quadrant where both the x-coordinate and y-coordinate are positive.
Since the x-coordinate is 9 and the y-coordinate is -10, which is negative, the point would be located in Quadrant 4.
