Look at the figure. How many different labeled rays are shown?

2 answers:

6 0

There are 10. A ray is a line with a dot on one end and an arrow on the other end. So just start at each dot and move to the arrow on either side. Or just count the dots and multiply by two since there are two arrows.

From the incorrect answer the other person gave us, I bet it's 2. Since E and A are the only two with technically no specified end. If I'm wrong I'll edit my answer.
