I Have some simple questions about PHYSICS PAPER 5, PLEASE READ

[jackrabbit]

Ok, when we draw a line of best fit, do we extend it so it reaches both the axis, or is there no need to extrapolate it?

AND, when they ask us for the gradient, do we also put in units for the gradient??

 

[larina]

no we dont extrapolate it
and no need for putting the units UNLESS they ASK for it.
