Answer 1

The green table shows a proportional relationship between x and y

Here, we want to select the table that shows a propoertional relationship between x and y

In the first table, we can establish that by multiplying the x-values by 4, we get the y-values

Thus, we can establish the relationship that;

`\begin{gathered} y\text{ = 4x} \\ or \\ x\text{ = }(y)/(4) \end{gathered}`

The same cannot be said for the second table as we cannot see a relationship between x and y (a proportional relationship)

With respect to this, we can see that it is the first table that shows the proportional relationship
