Required
Identify the unexplored point
Since the shaded region has been explored, an unexplored point will be located in the white region.
The given points are:
![(-5,2)\ (0,0)\ (4,3)\ (-2,4)](https://img.qammunity.org/2022/formulas/mathematics/high-school/srtt3ctkhodnenelpollmspdvb7rnhsagw.png)

In attachment 2, only (4,3) lies on the white region.
Hence, (4,3) has not been explored
