Why are they duplicates of the same point in the question?

According to desmos, the best fit line is \(y = 12.7288x + 24.678\), which you can round to \(y = 12.73x + 24.68\) or \(y = 13x + 25\) .

Hope this helps,

We need an exponential growth model, here

The function that ost cosely mdels the data   is

f(x)   = 11.7588 ( 1.4094 )^x   Nov 25, 2018
