I got y=4.467x-8760.425
I got y = 4.467x + 84.775 I think you might have used the wrong x-values. Did you use the years, or 0, 2, 4, ... Are you doing this by hand?
oh i used years that might have been the problem, I am using a ti-84 and I did get y = 4.467x + 84.775 but I put y=4.467x-8760.425 because I used the years.
ok yeah that's what it was
I am just wondering why do you have to use 0, 2, 4, etc. instead of the years?
for ease basically. The data only starts from 1980, if you're resetting that as "year 0". Keeping the years makes the data look smaller
Thank you, I have another problem, would you mind looking at it, I can will open another question, I have answers to it but im not sure if there right.
yeah no problem
Ok I see it now that makes more sense.
