To find the slope of the line that passes through the points \((2, 3)\) and \((10, 10)\), we use the formula for the slope \(m\):
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Here, \((x_1, y_1) = (2, 3)\) and \((x_2, y_2) = (10, 10)\).
Substituting the points into the formula:
\[ m = \frac{10 - 3}{10 - 2} \]
Calculating the differences:
\[ m = \frac{7}{8} \]
Thus, the slope of the line that passes through the points \((2, 3)\) and \((10, 10)\) is
\[ \boxed{\frac{7}{8}}. \]
