How can weight data be used as evidence for a given reaction idea? I just understand how one could just look at weight data and determine something without having to graph it. Could someone enlighten me? Thanks

Can you be more specific? Give an example of a data set and the process associated with gathering the data. Also, can you explain what you mean by "weight data" and "reaction idea"?

Hello Dan thanks for replying. Sorry I wasn't very specific. The type of weight data would be something like doing a hydrates lab to see how much water is lost when it is heated. Recording the weight before and after heating. I don't see how it would be possible, by just looking at the collected weight data, that anyone could come up with a reaction idea (in this case the reaction after hydrate is heated).

Can someone describe to me why the slope is relevant in a graph. I know it helps to see visually how close the points lie to the line, but how else is it relevant? Does the way it slant (45, 50, 60, 90 degree) also tell you something? For example: if my algrebraic formula was y=0.72x - 0.03

I know my slope is 0.72x and my y-intercept is -0.03, but why is it 0.72x - 0.03. I just don't understand. *sigh*
