The equation y=50x+30 represents the amount of money, y, in Amy’s savings account over time, x. The equation y=30x+50 represents the amount in Sally’s savings account. How does the graph of Sally’s account differ from the graph of Amy’s account?

• The graph representing Sally’s account starts lower on the y-axis.
• The graph representing Sally’s account starts closer to the origin.
• The graph representing Sally’s account is steeper.
• The graph representing Sally’s account is flatter.
