Line of Best Fit
describes how the points are distributed in a scatter plot
it is drawn through a set of data points only when there appears to
be a pattern
the line goes through as many points as possible
if there d

QUADRATICMODELS
Not all situations involve constant rates of change - for
those situations we must use non-linear models.
