To perform a 180-degree rotation counterclockwise about the origin, you can use the following transformation rule for each point \((x, y)\):
\[
(x, y) \rightarrow (-x, -y)
\]
Let's apply this transformation to each of the given points:
1. \((-2, 2)\):
\[
(-2, 2) \rightarrow (2, -2)
\]
2. \((-2, 4)\):
\[
(-2, 4) \rightarrow (2, -4)
\]
3. \((-4, 2)\):
\[
(-4, 2) \rightarrow (4, -2)
\]
4. \((-4, 4)\):
\[
(-4, 4) \rightarrow (4, -4)
\]
5. \((-5, 3)\):
\[
(-5, 3) \rightarrow (5, -3)
\]
So, the points after a 180-degree rotation counterclockwise are:
1. \((2, -2)\)
2. \((2, -4)\)
3. \((4, -2)\)
4. \((4, -4)\)
5. \((5, -3)\)
These are the new coordinates of the shape after the rotation.
