What is your reasoning behind choosing option D?

I used excel to calculate best-fit line, and I got D

could you take a screen shot of your excel file to review it?

hero · Answer

Explain how you used excel to find the line of best fit . How would anyone know that you know What you are doing?

anonymous · Answer

did you use the year for your x values and y for the amount gold produced?

vera_ewing · Answer

Yeah...that's what I was supposed to do, right?

anonymous · Answer

that's correct. I just put them into excel and im not coming up with D. Check to make sure you're using a linear trend line

vera_ewing · Answer

Ohh wait so it would be C, right?

anonymous · Answer

not quite, dont use best fit, use a linear trend line and if you entered all the data points correctly you shouldnt get c or d
