Solution:
we are given with the graph representing the linear model for the data .
we have been asked to find which line is a linear model for the data.
As we know the data can be represented using the linear model if most of the data values fall on the line or along the line(side by side) represented by the data model. There might be some extreme points which will not fall on the line.
So if we closely observe the graph, we find that in option B that most of the data points are lying on the line or side by side. There are also some extreme values which are exceptional.
Hence the best suited option is B.
