Question

what is a name for this line?

Explanation:

Step1: Recall line naming rules

A line can be named using two points on it. The symbol for a line is a double - headed arrow above the two - point label.

Step2: Analyze the options

• The first option \(AB\) is just the label of two points without the line symbol.
• The second option \(\overline{AB}\) is the symbol for a line segment (has two endpoints).
• The third option \(\overleftrightarrow{AB}\) is the correct symbol for a line (extends infinitely in both directions).

Answer:

\(\overleftrightarrow{AB}\)
