One method of estimating the uncertainty in the slope of a linear trend line from a plot that has uncertainty bars on each data point is to draw two straight

lines by hand. One with a minimum slope and the other with the maximum possible slope. You would then find the slope of the newly drawn lines and use them to calculate the uncertainty of the original trendline. How would you find the slope of the two newly drawn lines (min/max slope lines) ? * Make a best guess at the slope for each of the lines * Find the rise over run using two data points on each of the hand drawn lines. * Let the computer do it for you. * No answer text provided.
