As you mark points on a graph paper to represent something relative to another thing, you add up the dots to form a line or a curve.
The straight line is called the line of best fit because it can pass through many points.
If you get equal amounts on either side of the axis that will enable to have a straight line, you will get the best fit line that will go all through the points.

No, the best fit line shows the approximate value about the data. You can consider it like a mimic set that shows the trending data.
It is not essential that it passed through all the points but it can show the approximate terms that is extracted from that data. It can be used for forecasting and prediction.
