To find the constant of proportionality between the points (0, 0) and (4, 1), we can use the formula for the slope (m) of a line given by two points (x₁, y₁) and (x₂, y₂):
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Substituting the given points (0, 0) and (4, 1):
\[ m = \frac{1 - 0}{4 - 0} = \frac{1}{4} \]
Thus, the constant of proportionality is \(\frac{1}{4}\).
The correct response is:
1/4
