Question

what is the name of this figure?

Explanation:

A line has no endpoints and extends infinitely in both directions. A ray has one endpoint and extends infinitely in one direction. A line segment has two endpoints. The figure here has arrows at both ends, meaning it extends infinitely in both directions, and has points R and Q on it. So it's a line, specifically line RQ (or line QR) as it extends infinitely in both directions.

Answer:

Line \( RQ \) (or Line \( QR \))
