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.

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

Step-by-step 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

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
