To find the corresponding y value, put the value of x in the equation y=0.1x.
If by putting the x values from the table, we get the corresponding y values, then the table reprresent the equation y=0.1x.
Consider the x values in table G.
When x=5,

When x=10,

When x=15,

Similarly, when x=20, y=2.0 and when x=40, y=4.0.
So, the y values in table G satisfies the given equation.
Hence, option G is correct.
