can anyone tell me what is line of best fit?

line-best-fit.gif

a line that more or less passes through most of the points and distributes leftover points somewhat equally above n below it.
jxt found this on a website:
A line of best fit is a straight line that is drawn on a scatter plot to show the basic trend of the data
Line of Best Fit Rules
1. Count up the co-ordinates
2. Place your linear line with the trend!!!
3. Place the same number of points above the line, and the same number of points below the line.
4. Don't count the points on the line or the outliers.

Hey y'all
hi so I got this question dats been drivin every1 I know bananas.. so cn anyone answer it pls??? Its a physics question ^-^
A uniform metre rule of weight 0.9N is suspended horizontally by 2 vertical loops of thread A and B placed at 20cm and 30cm from its ends respectively. Find the distances from the centre of the rule at which a 2N weight must be suspended:
i) to make loop A become slack
ii) to make loop B become slack
Gud luck to you guys and please try your hands on it...any help at all is welcome... THNX A BUNCH!!!! :D
