A softball academy charges students an initial registration fee plus a monthly fee. The graph shows the total amounts paid by two students over a 4 month period. The lines are parallel.

Answer 1

I’m not exactly sure but Add how many there are

Answer 2

I can't actually see the graph but i'll try to help

Explanation:

if we use the formula y=mx+b

m=monthly fee

b=initial registration fee

x=amount of months charged

y=total sum paid

So you fill in the formula using the values on the graph
