ANSWER
y = 6x
EXPLANATION
Sam wants to write an equation to represent a proportional relationship.
The constant of proportionality is 6.
A proportional relationship is one where one value is related to another by a certain factor such that a change in one value will result in a proportional change in the other.
It is generally represented as:
[tex]\begin{gathered} y\text{ }\propto\text{ x} \\ \Rightarrow\text{ y = kx} \\ \text{where k = constant of proportionality} \end{gathered}[/tex]
Therefore, for Sam, the constant of proportionality is 6.
The equation to represent it will be:
y = 6x
So, Sam is wrong.
