Is a wriggly curve that goes through each one of them.
Best fit
a straight line
line of fit
Actually, two separate points are enough to determine the line.
Data points that are not close to the line of best fit are called outliers.

extrapolate
That is not true. It is possible for a data set to have a coefficient of determination to be 0.5 and none of the points to lies on the regression line.
linear graph
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 scatter plot would be best for non-related data points. A line graph would be best for related data points.

a line of best fit
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.
