<u>Answer:</u>
Option D
<u>Step-by-step explanation:</u>
In this table, the constant of proportionality, which is just the number that each <em>x</em> value is multiplied by to get the corresponding <em>y</em> value, is 7. This is because, as shown by the first row of the table, 1*7=7, and, as shown by the third row of the table, 3*7=21. Therefore, in the second row of the table, <em>y</em> should be 14, as 2*7=14, while in the fourth row of the table, <em>y</em> should be 28, as 4*7=28.
