Answer 1

To rotate a point \( (x, y) \) by \( 180^\circ \) counterclockwise about the origin, you can use the transformation:

\[
(x, y) \to (-x, -y)
\]

Now, we first move the given point \( (-4, 6) \) to the origin by translating it. However, since we are rotating about the point itself, we can directly apply the transformation as if it were about the origin:

1. **Translate the point to the origin:** This step is conceptually helpful but, in this case, we can just apply the transformation since we are rotating the point about itself.

2. **Apply the rotation:**
\[
(-4, 6) \to (-(−4), −6) = (4, −6)
\]

Therefore, the resulting point after rotating \( (-4, 6) \) by \( 180^\circ \) counterclockwise is:

\[
(4, -6)
\]

Thus, the answer is:

**(4, -6)**
