To find the coordinate of the midpoint of $\overline{QR}$, we can use the midpoint formula for a line segment on a number line. The midpoint formula is:

$\text{Midpoint} = \frac{x_1 + x_2}{2}$

where $x_1$ and $x_2$ are the coordinates of the two endpoints.

In this case, the coordinates of points $Q$ and $R$ are:

• $Q = -6$
• $R = -5$

Plugging these values into the formula, we get:

$\text{Midpoint} = \frac{-6 + (-5)}{2} = \frac{-11}{2} = -5.5$

So, the coordinate of the midpoint of $\overline{QR}$ is -5.5.
