To find the midpoint \( A \) of the line segment \( \overline{MB} \), we can use the formula for the midpoint:

\[ A = \frac{M + B}{2} \]

Given the values:

  • \( M = 5 \)
  • \( B = 9 \)

Substituting these values into the formula:

\[ A = \frac{5 + 9}{2} = \frac{14}{2} = 7 \]

Therefore, point \( A \) lies at \( 7 \) on the number line.
