WebSteps. To find the line of best fit for N points: Step 1 : For each (x,y) point calculate x 2 and xy. Step 2 : Sum all x, y, x 2 and xy, which gives us Σx, Σy, Σx 2 and Σxy ( Σ means "sum up") Step 3 : Calculate Slope m: m = N Σ … WebNov 24, 2024 · In this case it’s shown as m=1 and b=-0.8. That translates as y=1x-0.8. Finally, Desmos includes a valuable piece of information: R^2. That shows how accurate …
