To find the slope of the line that passes through the points \((2, 8)\) and \((-3, 14)\), we can use the formula for the slope \(m\):
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Here, we can assign:
- \((x_1, y_1) = (2, 8)\)
- \((x_2, y_2) = (-3, 14)\)
Now substituting the values into the slope formula:
\[ m = \frac{14 - 8}{-3 - 2} \]
Calculating the differences in the numerator and the denominator:
\[ m = \frac{6}{-5} \]
Thus, the slope of the line is:
\[ m = -\frac{6}{5} \]
So, the slope of the line that passes through the points \((2, 8)\) and \((-3, 14)\) is \(\boxed{-\frac{6}{5}}\).
