To calculate the midpoint \( M \) of the segment \( \overline{AB} \) given the points \( A(-1, 2) \) and \( B(4, -2) \), we use the midpoint formula:

\[ M = \left( \frac{x_A + x_B}{2}, \frac{y_A + y_B}{2} \right) \]

Where \( (x_A, y_A) \) and \( (x_B, y_B) \) are the coordinates of points \( A \) and \( B \).

For the coordinates of points \( A \) and \( B \):

  • \( A(-1, 2) \) means \( x_A = -1 \) and \( y_A = 2 \)
  • \( B(4, -2) \) means \( x_B = 4 \) and \( y_B = -2 \)

Now substituting these values into the midpoint formula:

\[ M = \left( \frac{-1 + 4}{2}, \frac{2 + (-2)}{2} \right) \] \[ = \left( \frac{3}{2}, \frac{0}{2} \right) \] \[ = \left( 1.5, 0 \right) \]

So, the coordinates of the midpoint \( M \) are \( (1.5, 0) \).

Therefore, the correct statement is:

M is located at (1.5, 0).
