Hi there!
The quadrant lV (4) is the quadrant in the bottom right of the graph.
Since the point is located in this cadrant :
The "x" coordinate will be positive (+) because the point is on the right side of the graph.
The "y" coordinate will be negative (-) because the point is at the bottom of the graph.
The coordinates of the point (x, y) would look like this : (+, -).
There you go! I really hope this helped, if there's anything just let me know! :)
