Given a set of coordinates:
(8, 80)
(14, 96)
(15, 98)
(16, 99)

Find an equation that suitably graphs these set of coordinates, and determine the y coordinate when x = 17, 18, and 19.

Thanks for all your help!

Do you have a TI calculator on you?

anonymous · Answer

Unfortunately not, I use desmos.com and web2.0calc.com, if that helps!

Well, this is a line of best fit graph. Um. Without a calculator I certainly can't do it by hand and I don't know how to do it in MMA. So... um ...

What would be the procedure to do by hand? I understand this is a logarithmic graph. Is there a way to find a line of best fit for a logarithmic graph?

You don't.
