How do I find the minumum/maximum acceptable slope?

[jayadds]

Given a scatter plot graph, how would you find the minimum/maximum acceptable slope?

I know that finding a gradient you would need to choose two points A(x1,y1) and B(x2,y2) and use the formula m = (y2-y1) / (x2-x1).

My question is, which two points to pick out to determine the minimum/maximum acceptable slope of a graph?

Many thanks.

Acceptable to whom? I think you'd need a criterion that could be applied, directing how much latitude you can apply to your line/s of "good fit". How did this question arise, may I ask?

Hi there :)

The question is attached to this response.

I can't read .doc media. Can you take a screen-shot and post as a gif or jpeg?

Here you go.

Looks like you'll need to turn back to Section 2.2 to find out how they determined their slope uncertainty.
