We will see that the line that best fits the data is the one in the first graph (top left one).
How to know which line best fits the relationship?
To know which line is the best one, what we need to do is:
- Measure the vertical distance between each point and the line.
- Add all of these distances.
- Find the graph such that the sum of these distances is the smallest.
I know that it is hard to do it with these graphs, as these are kinda small and the measure may be hard to take, so you can just estimate.
By doing that estimation you can see that (only for the two better graphs, I ignored the bottom two).
The first one has a total distance of near 10 units.
The second one has a total distance of near 11 units.
So the graph that fits best the data is the first one (top left).
