No, the best fit line need not go through any data point on a graph.

A discrete graph.
Line graph...
they are called error bars. It represents the amount of error associated with each data point
linear graph
It depends on what you are trying to do.
Maths
either a scatter graph or a line graph xx :)
line graph rock
