Step-by-step explanation:
You can use the Pick's theorem:
where
<em>i</em><em> - number of lattice points in the interior located in the polygon</em>
<em>b</em><em> - number of lattice points on the boundary placed on the polygon's perimeter</em>

Answer:
R' = (-2, -3)
Step-by-step explanation:
When a figure undergoes a 180degree rotation, both the (x) and (y) coordinates are multiplied by (-1). The coordinates of the given point are (2, 3). Multiply both of these numbers to fine (R'), that is point (R) after it undergoes its rotation. The coordinates of (R') are (-2, -3).
