In excel with a graph I have made from data that will be provided. I got the equation to be y=0.057x How can i get y=0.057x(x) I need this equation to be to the third sig fig value where now it is at 2. How does one go about doing this on excel? Here is my data I vs V where I was current and V was Voltage and showed a directly proportional relationship. Please set the equation to 0 before plotting. Please do not just tell me to load it on the grah and click equation, i understand that, I need to know how to expand this equation to the third sig fig which i believe is y=0.0570x please confirm via excel.. THANKS
