To find the constant of proportionality (k), we can use any pair of corresponding values from the table and substitute them into the equation y = kx. Let's choose the first pair of values (2, 4).
Substituting these values into the equation, we have:
4 = k * 2
To find k, we divide both sides of the equation by 2:
k = 4/2
k = 2
Therefore, the constant of proportionality (k) is 2. So, the correct answer is:
k = 2.0.
In her science classroom, Mrs. Hall noticed that the lengths (in inches) and weights (in ounces) of the class's pet ferret were directly related by the equation y = kx, where x is the length and y is the weight. Use the information in the table to find k, the constant of proportionality.
