Hi, does anyone know the answer to this question? I’m bad at geometry and I’m struggling to answer it.
### Midpoint of a Line Segment

A line segment has endpoints at \( A(-4, 11) \) and \( B(2, 3) \). Which of the following would be the coordinates of the midpoint of \( \overline{AB} \)?

1. \( (-1, 7) \)
2. \( (-6, 5) \)
3. \( (-2, 14) \)
4. \( (5, -4) \)

To find the midpoint of a line segment with endpoints \( A(x_1, y_1) \) and \( B(x_2, y_2) \), use the midpoint formula:

\[ \text{Midpoint} = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \]

Using the given coordinates \( A(-4, 11) \) and \( B(2, 3) \):

\[ x_1 = -4 \]
\[ y_1 = 11 \]
\[ x_2 = 2 \]
\[ y_2 = 3 \]

Substitute these values into the midpoint formula:

\[ \text{Midpoint} = \left( \frac{-4 + 2}{2}, \frac{11 + 3}{2} \right) \]
\[ \text{Midpoint} = \left( \frac{-2}{2}, \frac{14}{2} \right) \]
\[ \text{Midpoint} = (-1, 7) \]

Therefore, the coordinates of the midpoint of \( \overline{AB} \) are:
\[ (-1, 7) \]
