But if it is a linear function it doesnt matter if you only use two points. Unless the function is not linear. If the line isn’t completely smooth you could also use a polynomial function that would fit the curve. Unless it exhibits exponential behavior why would you ever model it as an exponential if linear or polynomial models the data more accurately?
But if the data originates from an exponential, any selection of two points will yield a different slope, because the data point lie not exactly on a straight line.
You suggested to model it linearly, that is what we are discussing here.
Your data, no because I have no access to the actually values. But just a plot of a line that seems very straight (but does not necessarily need to be), and measuring it manually will introduce some noise.
In my data, that I generated, yes there I know for a fact that it is from an exponential.
I am well aware what a graph is and that it shows the actually values, but to obtain some actually values to perform manually some calculations we need to extract some explicit values from the image. This is however not arbitrarily precise and therefore will add some noise to the extracted values.

Does the data originate from an exponential? Can you prove it?

The actual values are exactly as shown on the graph. Do you know what graphs are?
In your data what is the exponential function?

My data is simply y = exp(x).
That’s the curve of the line?
Your data as in you generated it? Or that’s the function that fits the curve shown in the graph?
In the case I am discussing, the data is generated using the exponential function exp(x).
Which case is that? Have we moved goal posts or are you claiming this line:
Was generated using the function y=exp(x)?
