Final answer:
The x-intercept of the graph represents the amount Jeremiah starts with in his bank account.
Step-by-step explanation:
The x-intercept of the graph represents the point on the x-axis where the graph intersects. In the context of Jeremiah's bank account, the x-intercept tells us the amount he starts with. This is because the x-axis represents time, and at the beginning (x = 0) his account balance is at the x-intercept.
