12 hours? If I'm wrong, sorry about that
Answer:
Yes
Step-by-step explanation:
The formula is x1+x2 divided by 2 and y1+y2 divided by 2.I hope this is what you where looking for
Given:
The table represents a proportional relationship.
To find:
The equation of the function.
Solution:
If y is directly proportional to x, then

...(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


Putting
, we get

Therefore, the correct option is A.
