Answer: 5.5 is the constant proportionality.

Step-by-step explanation:

Since we have given that

y = 5.5x

As we can see that

y is directly proportional to x.

So, mathematically written as

[tex]y\ \alpha\ x\\\\y=kx[/tex]

If we comparing both the expression, we get that

k = 5.5.

Hence, 5.5 is the constant proportionality.

The constant of proportionality of y = 5.5x is 5.5.

A directly proportional relational relationship can be represented below

  • y ∝ x

where

∝ = symbol for proportionality

y and x are the variable that are related. Therefore,

y = kx

where

k = constant of proportionality.

The equations y = 5.5x can be modelled as directly proportional relationship using y = kx.

Therefore, k = 5.5 is the constant of proportionality.

The constant of proportionality of y = 5.5x is 5.5.
