Answer:

4

Explanation:

Constant of proportionality is the same as slope in the context of a linear function, which is defined as Δy / Δx. We can find this by taking two points and finding the difference in their x- and y-coordinates.

I'll use (1, 4) and (2, 8).


\textrm{slope}=(8-4)/(2-1) = (4)/(1) = 4
