Question

which rays are part of line be?○ $overrightarrow{ac}$ and $overrightarrow{ae}$○ $overrightarrow{ab}$ and $overrightarrow{ae}$○ $overrightarrow{ac}$ and $overrightarrow{ab}$○ $overrightarrow{ab}$ and $overrightarrow{af}$

Explanation:

A line extends infinitely in both directions, and rays that lie on line BE must share the same straight path. Line BE passes through point A, with ray $\overrightarrow{AB}$ going from A through B (along one direction of line BE) and ray $\overrightarrow{AE}$ going from A through E (along the opposite direction of line BE). These two rays together form line BE.

Answer:

$\boldsymbol{\overrightarrow{AB}}$ and $\boldsymbol{\overrightarrow{AE}}$
