Here's why:
* Quadrants in the Coordinate Plane: The coordinate plane is divided into four quadrants.
* Quadrant I: x > 0 and y > 0
* Quadrant II: x < 0 and y > 0
* Quadrant III: x < 0 and y < 0
* Quadrant IV: x > 0 and y < 0
* The Point (9, 1): Since both the x-coordinate (9) and y-coordinate (1) are positive, the point falls within Quadrant I.
