To find the slope of a line given two points, you can use the slope formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
From your given points (4, 4) and (2, 2), we can assign:
- \( (x_1, y_1) = (2, 2) \)
- \( (x_2, y_2) = (4, 4) \)
Now plug these values into the slope formula:
\[ m = \frac{4 - 2}{4 - 2} = \frac{2}{2} = 1 \]
Thus, the slope of the line is:
\[ \boxed{1} \]
