To find the slope of the line passing through the points \((0, 4)\) and \((-8, -1)\), we can use the slope formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
where \((x_1, y_1) = (0, 4)\) and \((x_2, y_2) = (-8, -1)\).
Now, we can substitute the values into the formula:
\[ m = \frac{-1 - 4}{-8 - 0} \] \[ m = \frac{-5}{-8} \] \[ m = \frac{5}{8} \]
Thus, the slope of the line is \(\frac{5}{8}\).
