To find the slope of the line that passes through the points \((1, 5)\) and \((4, 10)\), we can use the slope formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Here, \((x_1, y_1) = (1, 5)\) and \((x_2, y_2) = (4, 10)\).
Substituting the coordinates into the formula:
\[ m = \frac{10 - 5}{4 - 1} = \frac{5}{3} \]
Thus, the slope of the line that passes through the points (1, 5) and (4, 10) is:
\[ \frac{5}{3} \]
