`[x]+[y]=5`
For `0 le x lt1, 0 + [y]=5 or [y]=5 or 5 le x lt 6`
Thus, the points lie in the region stisfying `0 le x lt 1 and 5 le x lt 6` as shown in the following figure.
Thus, we have the following values of x and the corresponding values of y.
The region satisfying the above conditions is as shown in the following figure.
