To find the slope of the line passing through the points \((-9, -3)\) and \((7, -7)\), we can use the slope formula:

\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]

Where \((x_1, y_1) = (-9, -3)\) and \((x_2, y_2) = (7, -7)\).

Substituting the values:

\[
m = \frac{-7 - (-3)}{7 - (-9)} = \frac{-7 + 3}{7 + 9} = \frac{-4}{16} = -\frac{1}{4}
\]

So, the slope of the line is:

\[
m = -\frac{1}{4}
\]
