For six hours a day Mrs. Lewis bakes cakes at a local bakery. She must record the number of cakes she has baked during the day on a time card. The graph below shows the number of cakes she had baked at various times during the day Monday.  How would the graph change if her data for Tuesday showed she baked 40 cakes that day?

• The graph would not change.
• The graph would not be as steep.
• The graph would be steeper.
• The graph would have a larger y-intercept.
