The mean of a set of data is the average, so when writing a conclusion or justifying a solution, instead of listing all your data you can say "the average of the data collected was _____"
Given:
The table represents a proportional relationship.
To find:
The equation of the function.
Solution:
If y is directly proportional to x, then
![y\propto x](https://tex.z-dn.net/?f=y%5Cpropto%20x)
...(i)
where, k is the constant of proportionality.
From the given table it is clear that the function passes through (2,1). So, the equation must be satisfied by the point (2,1).
Putting x=2 and y=1 in (i), we get
![1=k(2)](https://tex.z-dn.net/?f=1%3Dk%282%29)
![\dfrac{1}{2}=k](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%3Dk)
Putting
, we get
![y=\dfrac{1}{2}x](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B1%7D%7B2%7Dx)
Therefore, the correct option is A.
