Do I plot all the points then find the line of best fit?

OpenStudy (saifoo.khan):

Yes.

OpenStudy (camerondoherty):

Um... how do you find the line of best fit manually?

OpenStudy (saifoo.khan):

You can't. Line of best fit is something like: http://www.bbc.co.uk/schools/gcsebitesize/maths/images/graph_55.gif You can only find it once plotted.

OpenStudy (camerondoherty):

I mean when you plot it how do you find the equation... sorry i wasnt specific lol...

OpenStudy (saifoo.khan):

Take any two points on the line. Find the gradient and so on.

OpenStudy (camerondoherty):

OpenStudy (saifoo.khan):

Slope.
