To find the constant of proportionality (k), we can use any pair of values from the table. Let's use the first pair of values: x = 12 inches and y = 24 ounces.
We can substitute these values into the equation y = kx:
24 = k * 12
To solve for k, divide both sides of the equation by 12:
k = 24/12
Simplifying, k = 2.
Therefore, the constant of proportionality (k) is 2.
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.
