The question asks for the slope of the line passing through the points $(2, 4)$ and $(6, 6)$. To calculate the slope $m$, we use the slope formula:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Here, $(x_1, y_1) = (2, 4)$ and $(x_2, y_2) = (6, 6)$.

Substituting the values into the formula:

$m = \frac{6 - 4}{6 - 2} = \frac{2}{4} = \frac{1}{2}$

Thus, the slope of the line is $\frac{1}{2}$.
