Answer:
Proportionality constant =

Explanation:
Let y ∝ x
y = kx
Here, k = proportionality constant
From the table attached,
If x = 2 and y = 3,
3 = 2k
k =

If x = 4 and y = 6,
6 = 4k
k =

k =

Since, k =
is constant in every condition, table represents the proportional relation with proportionality constant
