Given the equation :
![y=(3)/(8)x](https://img.qammunity.org/2023/formulas/mathematics/college/62tw0ji6qzi2qfild20et4nnx0vmfhfgw9.png)
Which represent proportional relationship between x and y.
So, the general form of the proportional relationship between x and y is :
y = k * x
So, by comparing the equations :
k = 3/8
so, the answer is : the constant of proportionality = 3/8
