The order in which we write the letters in a ray is important. The first letter indicates the starting point of the ray, and the second letter indicates any other point on the ray as it extends to infinity. Therefore, $\overrightarrow{LM}$ is a ray that starts at point $L$ and goes through point $M$ while $\overrightarrow{ML}$ is a ray that starts at point $M$ and goes through point $L$.
