The point a(-3,6) is in 2nd quadrant.
If we interchange the signs of coordinates, it become (3,-6) and it will lie on 4th quadrant.
------------------------------------------------------------------------------------------------
1st quadrant → (+, +)
2nd quadrant → (-, +)
3rd quadrant → (-, -) 
4th quadrant → (+, -)
