To find the midpoint \( M \) of the line segment with endpoints \( A(-3.2, 3.5) \) and \( B(2.1, -2.3) \), you can use the midpoint formula:

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

where \( (x_1, y_1) \) are the coordinates of point \( A \) and \( (x_2, y_2) \) are the coordinates of point \( B \).

Substituting the coordinates of \( A \) and \( B \):

\[ M = \left( \frac{-3.2 + 2.1}{2}, \frac{3.5 + (-2.3)}{2} \right) \]

Calculating each component:

  1. For the x-coordinate: \[ \frac{-3.2 + 2.1}{2} = \frac{-1.1}{2} = -0.55 \]

  2. For the y-coordinate: \[ \frac{3.5 - 2.3}{2} = \frac{1.2}{2} = 0.6 \]

Thus, the midpoint \( M \) is:

\[ M = (-0.55, 0.6) \]

So the midpoint of segment \( AB \) is \( (-0.55, 0.6) \).
