Case(i)
The point E is at a distance of +3 units from y-axis and at a distance of +4 units from x-axis.
Therefore, the x coordinate of E is 3 and y coordinate is 4.
Hence the coordinate of E are (3,4).
Case(ii)
The point F is at a distance of -3 units from y-axis and at a distance of -4 units from x-axis.
Therefore, the x coordinate of F is -3 and y coordinate is -4.
Hence the coordinate of F are (−3,−4).
