Ineed with this question for a grade

C, because the slope is 17.63 which is dollars per week. We know this because in the equation y=mx+b, m stands for the slope which in this case is 17.63. The graphs shows that each week Aidan saves an additional $17.63 to his already saved $27.52 (which is the y intercept). He already has that much money saved because that is where the graph starts, not at 0 which would mean he had no additional money saved.

The answer is that the rate of change is $50 per 1 monthhope this ; )
