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 type of graph would be best for data points?
A scatter plot would be best for non-related data points. A line graph would be best for related data points.
In a data plot most of the data points will lie below the line of best fit?
If most of them lie below the line, then that line isn't the best fit. The exact layout depends on what definition you use for "best fit", but any definition will produce a line that has roughly the same number of data points on each side of it.
A line of best fit will go through all of the plotted data points?
false
Does the best-fit line have to go through all data points on a graph?
False
In a data plot about half the data points will lie below the line that best fits?
Yes. The exception arises when you have outliers.
What type of graph would be best for data points?
A scatter plot would be best for non-related data points. A line graph would be best for related data points.
A line that best fits the data points on a scatter plot?
A straight line which best describes the data on a scatter plot is called a "line of best fit". The line could pass through some of the points, all of them, or none of them.
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 a best-fit-line?
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.
What is the line graph in which the data points do not fall along a straight line?
a line of best fit
What is a line graph in which the data points do not fall along a straight line is?
a line of best fit
What is A line graph in which the data points do not fall along a straight line?
a line of best fit
Does a best fit line connect all of the data points in a line graph?
yes
What is a line that comes as close as possible to data points as possible?
line of best fit.
What is a graph in which the data points do not fall along a straight line?
a line of best fit
In data plot most of the data points will lie below the line of best fit?
False
What is a line of best fit as a science definition?
a line drawn on a graph to reveal data points
