more specifically into slope-intercept form (y=mx+b)

Answer 3

b is basically youre starting point (how many trains did he start his collection with?)

1

ok so now you have y=mx+1

Answer 6

from there, the m can basically be your rate of change (how many did he add per x < in your case years)

Answer 7

he adds 2

Answer 8

ok so now you have y=2x+1. now all you need to do is find that graph

Answer 9

oh ok so it is B
