1. Estimating a value between two known values in a data set is called INTERPOLATION.
2. The slope of a line models the RATE OF CHANGE (INCREASE OR DECREASE) of a function
3. The form of a linear equation that shows the slope and one point is the SLOPE - INTERCEPT FORM.
4. Two lines are perpendicular when slopes HAVE OPPOSITE SIGNS or VALUES ARE RECIPROCAL. <span> 5. That line that most accurately models data in a scatter plot is the LINE OF BEST FIT.</span>
