To calculate the slope of the line using the given points \((11, 7)\) and \((14, 4)\), we can use the formula for the slope \(m\):
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Here, \((x_1, y_1) = (11, 7)\) and \((x_2, y_2) = (14, 4)\).
Substituting the values into the formula:
\[ m = \frac{4 - 7}{14 - 11} = \frac{-3}{3} = -1 \]
Thus, the slope of the line is \(-1\).
