Explanation for Coordinates of A:
The distance of point A from y-axis is 3 units and from x-axis is 1 units.
A lies in the first quadrant, so both the coordinates are positive.
This implies, coordinates of A are (3,1).
Similarly other points are,
A (3,1), B (6,0), C (0,6), D (-3,0), E (-4,3), F (-2,-4), G (0,-5), H (3,-6), P (7,-3), Q (7,6)
