i have a graph that i fitted a line on it using least squares fit. Now i want to calculate the uncertainty of slope. i calculated the standard error of slope and now i have this question:

the uncertainty of slope is "slope ± standard error" or it is the confidence interval???!

please help me. i really need the answer. i searched in many books but unfortunately i couldn't find the answer.
