Point A
lies at
on the number line.
1 answer
To find the midpoint A of the line segment MB, we can use the midpoint formula:
\[ A = \frac{M + B}{2} \]
Where \( M = 5 \) and \( B = 9 \).
Substituting the values:
\[ A = \frac{5 + 9}{2} = \frac{14}{2} = 7 \]
Therefore, point A lies at 7 on the number line.
