Not necessarily. Often it is, but the line of best fit is simply an equation that closely matches the results. Therefore any line could be a line of best fit, linear, quadradic, or even cubic! The sky (and the results) are the limit.
The line of best fit does not have to pass through the 0 (origin) and rarely does
The line of best fit is simply the line that shows the general direction of the graph. The trick is to make the line go through as many points on the graph as possible. Some scatter plots have no line of best fit.
The best fit line is basically the average of a graph; it represents where, when, etc. the majority of the event occurred.
Data points that are not close to the line of best fit are called outliers.
the dependent variable has one value and the independent variable has no value
Because the "best fit" line is usually required to be a straight line, but the data points are not all on one straight line. (If they were, then the best-fit line would be a real no-brainer.)
A straight line equation
if you are reffering to a scatter graph, the straight line is called the line of best fit.
The straight line that best fits the data on a coordinate plane is the Line Of Best Fit.

"Line of best fit"
A best-fit line is the straight line which most accurately represents a set of data/points. It is defined as the line that is the smallest average distance from the data/points. Refer to the related links for an illustration of a best fit line.
