Answer:

The constant of proportionality is equal to 2.5.

Step-by-step explanation:

The given equation is .

Now, let's assume y is proportional to x.

Mathematically, it can be written as,

Now, to eliminate the sign of proportionality by equal to, it is required to introduce a constant term. It can be represented as,

Now, compare the given equation with the above equation,

The above comparison concludes that the constant of proportionality is equal to 2.5.
