Look at how Sara drew her axes. What seems strange?

  1. First quadrant graph,  x axis has 4, equally spaced, marks, labeled, 1, 2, 3, 4. y axis has 4, equally spaced marks, labeled, 1, 2, 4, 8. Points on the graph are: (0, comma 1), (1, comma 2), (2, comma 4) and (3, comma 8).

    Notice the intervals on the .
