Solution

To find the image of a point after a 180-degree rotation about another point, you can use the formula for rotating a point in a plane. The formula for a 180-degree rotation about the point (h, k) is:

(x', y') = (2h - x, 2k - y)

where (x, y) is the original point and (x', y') is the image of the point after rotation.

Given that the original point P is (3, 4) and the center of rotation is (2, 3), we can substitute these values into the formula:

P' = (22 - 3, 23 - 4) = (1, 2)

So, the image of point P after a 180-degree rotation about (2, 3) is P'(1, 2).
