The correct option is B No
A graph of direct variation always passes through the origin. This is not true for the given graph, thus this cannot represent direct proportionality.
Also, we know, for direct proportionality,
yx=k, where k is the constant of proportionality.
If we take values of x and y from the given figure, to determine k, we see that:
For y=3 and x=6,
k=36=0.5
And, for y=8 and x=9,
k=89=0.89
Since the value of k is not constant, we cannot call this graph a representation of direct variation.
Option (b.) is correct.
