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

"Line of best fit"
line of best fit.
False. When solving for the slope of the best fit line, you should consider all data points in your dataset to find the line that best fits the overall trend. Choosing points closest to the line or on the line may bias your results and not accurately represent the relationship between the variables.
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.
