What is bigger 10 pounds or 10 kilograms

In this item we are to determine which among the given measurements with the same numerical value but with different units is bigger or larger than the other. To do so, we simply have to convert one unit to the other to establish consistency. In this item, it is chosen that pounds be converted to kilograms.
(10 pounds)(0.4536 kg / 1 pound) = 4.536 kilograms
 Since, the equivalent of 10 pounds in kilograms is much smaller than the given 10 kilograms hence, the answer is 10 kilograms is bigger.

The correct answer would be shape of function b = 2× slope of function a.
