In chemistry
How exactly are we supposed to draw the graphs?
When do we draw the curve, line of best fit
do we avoid anamalous points...
and when do we draw two lines cutting one another
Please tell me anything about graphs in chemistry paper 6
It depends on the question.
Curve is when they say smooth line graph( mostly rate questions have this type),linemof best fit is one usually one point doesn't exactly fit in with the rest of the points.
Yes,anomalous points (usually there'd be one or two) should be ignored when drawing the best-fit line.
This again depends on the question after you plot the points you'll see.

Take a look at this:
