Usually when there's 2 dots(data points), you can place a line.
When there's more data points, there's way to calculate "best line" that reduces error to the minimum. So kind line best choice of approximate line that defines these dots.

Does the line of best fit have to start from the origin?
The line of best fit does not have to pass through the 0 (origin) and rarely does
How do you find a line of best fit from scatter plot?
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.
Does the line of best fit have to be straight?
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.
What is the purpose of a best fit line?
The best fit line is basically the average of a graph; it represents where, when, etc. the majority of the event occurred.
What are the points that don't follow the line of best fit called?
Data points that are not close to the line of best fit are called outliers.
What is the name of a line on a graph?
you mean line of best fit?
What does account for any deviations in your data from the best-fit line in concrete terms mean?
It means that you need to give reasons why every point was not on the best fit line.
What is a line of fit?
a line of fit mean perfect line.
Why does the line of best fit have to start from 0?
The line of best fit does not have to start from 0.
Is the best fit line the same as the line of best fit?
Yes but phrased differently
What is a line of best fit on a line graph?
The line that minimized the sum of the squares of the diffences of each point from the line is the line of best fit.
What is a line that is not a line but is almost a line?
A line of best-fit.
Why does best fit line does not touch all data points?
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.)
What is the difference between a trend line and a line of best fit and how are they useful in analyzing data?
What is the difference between a trend line and a line of best fit
Why is a best fit line used?
The line of best fit is the best possible answer you can get from raw data. They also can be used to make predictions.
Does the line of best fit have to start from the origin?
The line of best fit does not have to pass through the 0 (origin) and rarely does
What is the process of finding line of best fit called?
Finding the line of best fit is called linear regression.
