The constant of proportionality for the table that has been shown is 4.
What is the constant of proportionality?
A factor that connects two quantities that are exactly proportionate to one another is known as the constant of proportionality. A constant multiple of the other quantity characterizes a proportionate relationship.
It is significant to remember that the notion of the constant of proportionality is frequently applied to linear connections, in which the relationship's graph is a straight line that passes through the origin (0, 0).
We can see that the both quantities are increasing hence this is a direct proportionality
Thus x α y
x = ky
k = x/y
k = 8/2
k = 4
