Answer:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
where
k is the constant of proportionality
In this problem we have
so
the constant of proportionality k is equal to
therefore
the answer is
Step-by-step explanation:The constant of proportionality in the equation is
Further explanation:
The relation is defined as the relationship between the input values and output values.
The x coordinates are the domain of the function and the y coordinates are the range of the function.
Given:
The equation is
Explanation:
The proportionality equation can be expressed as follows,
The value of changes as changes. If the value of increases then the value of y is also increasing.
The equation can be expressed as follows,
The inversely proportional relationship can be expressed as,
Here, is the proportionality constant.
The given equation is
The y is the independent variable and is the dependent variable.
The proportionality constant is 2.5.
The constant of proportionality in the equation is
