What value completes the y-column?

12

Step-by-step explanation:

We are given that the table shows a proportional relationship between x and y. This can be represented by the equation, y = mx. Where k is the constant of proportionality.

Using the first pair given, (4, 16), let's find k.

k = y/x = 16/4

k = 4

Substitute k = 4 into y = kx

We have,

y = 4x

To find the value that completes the y-column, plug in the value of x into y = 4x.

x is given as 3.

Thus:

y = 4(3)

y = 12
