Answer :
Step-by-step explanation:
To find the length of the line segment joining -6 and -10 on the number line, we calculate the absolute difference between these two points.
The points -6 and -10 are positions on the number line. The length of the line segment between them is:
\[ |-10 - (-6)| \]
Simplify the subtraction inside the absolute value:
\[ |-10 + 6| \]
\[ |-4| \]
Since the absolute value of -4 is 4, the length of the line segment joining -6 and -10 is \( \boxed{4} \).
