Step-by-step explanation:
To check where there is a direct relationship between x and y, we need to check whether all the x,y pairs we have fit some rule:
.
For the first pair (x=4, y=6.4),
Therefore .
For the second pair (x=7, y=11.2),
Therefore .
For the third pair (x=10, y=16),
Therefore .
For the second pair (x=13, y=20.8),
Therefore .
So x does directly vary with y, and we have found out that .
