As I know, it is like this...
From the bottom point you have put, you connect it till the end point with just a straight line. You don't follow every points as that isn't line of best fit.
Hope that did help! :)

When is it impossible to draw a line of best fit?
if you only have one point
Is it ALWAYS possible to draw a line or curve of best fit in a scatter plot?
yes
What is a best fit line on a graph?
When points are marked on a graph, a line is often drawn across the dots plotted. A line of best fit is a straight line that goes through as many of such points as possible.
Why is it preferable to draw a line of best fit rather than to connect the dots?
show a trend
When should I draw a smooth curve a best fit line or only join the plots (I am especially thinking about Biology for that last one)?
You should use a curve if the scatter plot shows a clear curving shape. Otherwise draw a straight line. But a line of best fit should never zigzag from point to point.
How do you make a best fit line graph?
You want to draw a line through your plotted points and try to get equal amounts on either side.
Does the trend line always pass through every point on a scatter plot?
No. When you draw a best line of fit on the scattered plot, the line would not be straight.
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?
