To determine the constant of proportionality and the equation for the weight of the ferret based on its length, we need a pair of values from the table indicating both the weight and the corresponding length of the ferret.
The relationship states that the weight \(y\) varies directly with the length \(x\), which can be expressed mathematically as:
\[ y = kx \]
where \(k\) is the constant of proportionality.
To find \(k\), you can use a specific pair of values from the table (once you provide it), such as:
\[ k = \frac{y}{x} \]
After calculating \(k\), you can substitute it back into the equation:
\[ y = kx \]
Please provide the specific values from the table, and I can help you find the constant of proportionality and complete the equation!
