\( U(9,2) \) and \( V(20,6) \) are the endpoints of a line segment. What is the midpoint \( M \) of that line segment? Write the coordinates as decimals or integers. \( \quad M=(\square \)

To find the midpoint \( M \) of the line segment defined by the endpoints \( U(9,2) \) and \( V(20,6) \), we use the midpoint formula: \[ M\left( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} \right) \] Substituting the coordinates of points \( U \) and \( V \): \[ M\left( \frac{9+20}{2}, \frac{2+6}{2} \right) = M\left( \frac{29}{2}, \frac{8}{2} \right) = M(14.5, 4) \] So, the coordinates of the midpoint \( M \) are \( M=(14.5, 4) \).
