Final answer:
Point A (1,3) is located in Quadrant 1 of the Cartesian coordinate system, where both x and y values are positive.
Step-by-step explanation:
The point in question is Point A (1,3). In the Cartesian coordinate system, the x-coordinate represents the position along the horizontal axis, while the y-coordinate indicates the position along the vertical axis. A positive x-coordinate and a positive y-coordinate, as seen in the coordinates (1,3), place Point A in Quadrant 1. This is the upper right quadrant where both values are positive.
