Answer :
Step-by-step explanation:
To find the length of the line segment joining 5 and -5 on the number line, we calculate the absolute difference between these two points.
The points 5 and -5 are positions on the number line. The length of the line segment between them is:
\[ |5 - (-5)| \]
Simplify the subtraction inside the absolute value:
\[ |5 + 5| \]
\[ |10| \]
Since the absolute value of 10 is 10, the length of the line segment joining 5 and -5 is \( \boxed{10} \).
