Step-by-step explanation: In this problem, we are asked to draw an example of ray <em>EF</em>.
When representing a ray, the first point in this case <em>E</em> is always the endpoint. The second point in this case <em>F</em> always indicates the direction. So, we have ray <em>EF</em>.
It's important to understand that our ray can go in any direction. For example, the following figure also represents ray <em>EF </em>even if it was going to the left. This is because <em>E </em>is still the endpoint and <em>F</em> still indicates the direction.
