To find the slope of the line that passes through the points \((-10, -1)\) and \((5, -4)\), we can use the formula for slope (m):
\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]
where \((x_1, y_1)\) is \((-10, -1)\) and \((x_2, y_2)\) is \((5, -4)\).
Substituting the values in:
\[
m = \frac{-4 - (-1)}{5 - (-10)}
\]
This simplifies to:
\[
m = \frac{-4 + 1}{5 + 10} = \frac{-3}{15}
\]
Now, simplifying \(-3/15\):
\[
m = -\frac{1}{5}
\]
Thus, the slope that passes through the two points is:
\[
\boxed{-\frac{1}{5}}
\]
Therefore, the correct answer is B. \(-\frac{1}{5}\).
\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]

Substituting the values in:

This simplifies to:
\[
m = \frac{-4 + 1}{5 + 10} = \frac{-3}{15}

Now, simplifying \(-3/15\):
\[
m = -\frac{1}{5}

Thus, the slope that passes through the two points is:
\[
\boxed{-\frac{1}{5}}

Therefore, the correct answer is B. \(-\frac{1}{5}\).
