To find the constant of proportionality, we can use any pair of values from the table. Let's use the first pair of values, (2, 4):
y = kx
4 = 2k
To solve for k, we divide both sides of the equation by 2:
4/2 = 2k/2
2 = k
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. (1 point) Responses k = 2.0 k = 2.0 k = 2.5 k = 2.5 k = 1.5 k = 1.5 k = 3.0 k = 3.0 Skip to navigation
