if a reaction is first order, does the line of best fit HAVE to start from 0,0? or can it start from anywhere along the Y-axis?

Thanks

if its in first order the line of best fit has a gradient of 1, it wouldnt go through (0,0) unless the concentration is 0 and then surely it wouldnt work because if its order 1 it would have an effect! hmmm not sure but i dont think it does! as i dont think my coursework ones do? sorry if im rong but im pretty sure u dont have to go thru (0,0)
