To find the slope of the line that passes through the points \((1, 7)\) and \((10, 3)\), we can use the slope formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
where \((x_1, y_1) = (1, 7)\) and \((x_2, y_2) = (10, 3)\).
Substituting the values into the formula, we get:
\[ m = \frac{3 - 7}{10 - 1} \]
Calculating the differences:
\[ m = \frac{-4}{9} \]
Thus, the slope of the line that passes through the points \((1, 7)\) and \((10, 3)\) is
\[ \boxed{-\frac{4}{9}}. \]
