Answer:
Constant of proportionality in the given equation is, 2.5
Step-by-step explanation:
The Direct proportionality says that:
[tex]y \propto x[/tex]
then, the equation is of the form : y = kx .....[1] where k is the constant of proportionality.
Given the equation: [tex]y = 2.5x[/tex]
On comparing given equation with [1] we get;
k = 2.5
Therefore, constant of proportionality in the given equation is, 2.5
