$\left(6.85 , 3.3\right)$

Explanation:

For this, we will use the midpoint formula: $M = \left(\frac{{x}_{1} + {x}_{2}}{2} , \frac{{y}_{1} + {y}_{2}}{2}\right)$, which basically involves finding the middle of the x coordinates, and the middle of the y coordinates.
- ${x}_{1}$ and ${y}_{1}$ are the coordinates of the first point $\left(5.6 , - 2.8\right)$
- ${x}_{2}$ and ${y}_{2}$ are the coordinates of the second point $\left(8.1 , 9.4\right)$
- It doesn't matter which one we call the first or second point

Applying the formula:
$M = \left(\frac{5.6 + 8.1}{2} , \frac{- 2.8 + 9.4}{2}\right)$
$= \left(\frac{13.7}{2} , \frac{6.6}{2}\right)$
$= \left(6.85 , 3.3\right)$
