To find the slope of the line that passes through the points \((-5, 7)\) and \((-2, 4)\), we can use the slope formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Here, \((x_1, y_1) = (-5, 7)\) and \((x_2, y_2) = (-2, 4)\).
Now, substituting the coordinates into the formula:
\[ m = \frac{4 - 7}{-2 - (-5)} \]
Calculating the numerator:
\[ 4 - 7 = -3 \]
Calculating the denominator:
\[ -2 - (-5) = -2 + 5 = 3 \]
Now we put the numerator and the denominator together:
\[ m = \frac{-3}{3} \]
Simplifying this gives:
\[ m = -1 \]
Thus, the slope of the line that passes through the points \((-5, 7)\) and \((-2, 4)\) is \(\boxed{-1}\).
