To find the slope of a line that passes through two points \((x_1, y_1)\) and \((x_2, y_2)\), you can use the formula for the slope \(m\):
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
In this case, the points are \((2, 3)\) and \((0, 11)\). Assigning the variables:
- \( (x_1, y_1) = (2, 3) \)
- \( (x_2, y_2) = (0, 11) \)
Now plug in the values into the slope formula:
\[ m = \frac{11 - 3}{0 - 2} \]
Calculate the numerator and the denominator:
\[ m = \frac{8}{-2} \]
Simplify the fraction:
\[ m = -4 \]
Thus, the slope of the line is \(\boxed{-4}\).
