From a set of graphed data the slope of the best fit line is
 From a set of graphed data the slope of the best fit line is found to be 1.93 m/s and the slope of the worst fit line is 1.23 m/s. Determine the uncertainty for the slope of the line. 
 
 That and what formula did you use to find them. Thank you

Solution
Note that
delta B1 = |B1(best) - B1(worst)| = |1.93 m/s - 1.23 m/s|
= 0.70 m/s [ANSWER]
