Hi,

How could I find the line of best fit? I plotted each of the equations I had for a problem I'm solving. The equations were linear (y=ax+b) and quadratic (y=ax+b+c). I'm supposed to find out which line is the most appropriate for the data that is given to me. When looking at the scatterplot I can't tell which line fits best.
