The constant of proportionality = 2

Step-by-step explanation:

Two quantities P and Q are said to be proportional if for P ∝ Q iff $\frac{P}{Q} = k$

Here, k = Proportionality Constant

Now, here given

Case 1: x = 2, y = 1

So, $k = \frac{x}{y} = \frac{2}{1} = 2$

Case 2: x = 4, y = 2

So, $k = \frac{x}{y} = \frac{4}{2} = 2$

Case 3: x = 6, y = 3

So, $k = \frac{x}{y} = \frac{6}{3} = 2$

Case 4: x = 8, y = 4

So, $k = \frac{x}{y} = \frac{8}{4} = 2$

So, in each case we observe that the value of k = 4

Hence the constant of proportionality = 2
