A coordinate graph shows the x-axis labeled as months ranging from 0 to 10 in 1 unit increments and the y-axis labeled as dollars ranging from 0 to 700 in increments of 100. Four unlabeled points are plotted as follows: left parenthesis 0 comma 200 right parenthesis, left parenthesis 2 comma 300 right parenthesis, left parenthesis 4 comma 400 right parenthesis, and left parenthesis 6 comma 500 right parenthesis. A solid arrow passes through these points.

To determine which graph accurately represents Jane's savings over time, we need to analyze her savings account activity:

  1. Initial Deposit: Jane starts with $200.
  2. Monthly Deposit: She deposits an additional $100 every month.

We can calculate her total savings at the end of each month:

  • Month 0: \( 200 + 0 \times 100 = 200 \)
  • Month 1: \( 200 + 1 \times 100 = 300 \)
  • Month 2: \( 200 + 2 \times 100 = 400 \)
  • Month 3: \( 200 + 3 \times 100 = 500 \)
  • Month 4: \( 200 + 4 \times 100 = 600 \)
  • Month 5: \( 200 + 5 \times 100 = 700 \)
  • Month 6: \( 200 + 6 \times 100 = 800 \)

Now let's compare the graphs based on the calculated points:

  • (0, 200)
  • (1, 300)
  • (2, 400)
  • (3, 500)
  • (4, 600)
  • (5, 700)
  • (6, 800)

From the descriptions of the provided graphs, the correct graph should show the points calculated above:

  • The second graph shows:
    • \( (0, 200) \)
    • \( (1, 300) \)
    • \( (2, 400) \)
    • \( (3, 500) \)

This graph shows the correct increases each month, indicating that Jane adds $100 monthly in addition to her initial deposit.

Therefore, the second graph correctly illustrates how much money will be in her savings account over time.
