Answer: not proportional
Step-by-step explanation:
The constant is called the coefficient of proportionality if one variable is always the product of the other variable and a constant. And the variables are said to be directly proportional.
In the given table , let the variables are proportional then the constant of proportion(k)=[tex]\frac{y}{x}[/tex]
[tex]\Rightarrow\ k=\frac{3}{2}[/tex]=1.5
[tex]\Rightarrow\ k=\frac{7}{4}[/tex]=1.45
⇒ k is not a constant of proportionality.
⇒ the variables x and y are not proportional.
