To find the constant of proportionality between the two points (0, 0) and (4, 1), you can use the formula for the slope of a line (which also represents the constant of proportionality in a linear relationship):
\[ k = \frac{y_2 - y_1}{x_2 - x_1} \]
Here, we can assign the points as follows:
- Point 1: \((x_1, y_1) = (0, 0)\)
- Point 2: \((x_2, y_2) = (4, 1)\)
Now substituting the values into the formula:
\[ k = \frac{1 - 0}{4 - 0} = \frac{1}{4} \]
Thus, the constant of proportionality is \(\frac{1}{4}\).
