In the image, a ray is depicted with points labeled from $G$ to $J$, and the arrow points to the left.

A ray is defined as part of a line that starts at one point and extends infinitely in one direction. The ray is named starting from its endpoint and using another point on the ray to indicate its direction.

• The arrow is pointing to the left, which means the ray starts from $J$ and extends to the left.
• To name this ray, we start from point $J$ and include another point to indicate the direction. Using $J$ and $G$ (since $G$ is in the direction of the arrow):

The ray is named as $\overrightarrow{JG}$.
