For example:
Graph:
Volume pH Slope
0.00 2.05 .......
0.95 2.06 ..........
1.90 2.07 .............
2.82 2.07 ................
So on and so on...
For example I need to find for each piece of data the change inpHover the change in volume. That will find me the slope. How canIget excel to do that?
Eventually I will find the equivalence point. I think I know howtodo that. (It's the one with the largest slope).

Here is the graph:
