Answer:

To answer this,  

It has said that two sets of values have a direct variation, or said to be directly proportional if y = kx, where k is the constant of variation.

This means that whatever you do to the x, the same applies to the y. So, for example, if you double the x, you also double the y as well.

Also, make sure to make y the dividend while x is the divisor.

In order to check the shown tables for variation, we should divide y by x, and it should result to an accurate quotient.

(X) = 4

(Y) 32

Divide y by x.

32 ÷ 4 = 8

Therefore, the constant of variation should be 8. (k = 8).

But, if you are asking for the equation, it should be y = 8x.

Hope it helps!
