Construct a log plot of the given data. Then approximate a relationship of the form y=Ax^c.

x=Land Area Y= bird species count

30 25

200 30

20,000 80

25,000,000 170

1,000,000,000 250

I calculated each value using log. I found the new values but I don't know how to do the approximation. The first value is (1.4771,1.3979) and the last one is (9,2.3979).

Also I found the slope which is 1/7.5229. I don't know if I need it though.
