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.
