The problem asks us to graph the image of triangle $LMN$ after a 180-degree counterclockwise rotation around the origin. From the graph, the coordinates of the vertices of triangle $LMN$ are approximately $L(-4, 7)$, $M(1, 7)$, and $N(-4, 6)$.

1. Problem Description

The problem asks us to graph the image of triangle LMNLMN after a 180-degree counterclockwise rotation around the origin. From the graph, the coordinates of the vertices of triangle LMNLMN are approximately L(4,7)L(-4, 7), M(1,7)M(1, 7), and N(4,6)N(-4, 6).

2. Solution Steps

A 180-degree rotation around the origin transforms a point (x,y)(x, y) to (x,y)(-x, -y). Therefore, we apply this transformation to the coordinates of LL, MM, and NN.
The coordinates of LL' are ((4),7)=(4,7)(-(-4), -7) = (4, -7).
The coordinates of MM' are (1,7)(-1, -7).
The coordinates of NN' are ((4),6)=(4,6)(-(-4), -6) = (4, -6).

3. Final Answer

The coordinates of the vertices of the rotated triangle LMNL'M'N' are L(4,7)L'(4, -7), M(1,7)M'(-1, -7), and N(4,6)N'(4, -6).
(Note: The solution only provides the coordinates. To fully answer the question, you would need to plot these points on a coordinate plane and connect them to form the triangle.)
