The graph below shows the number of pages that Victor has left to read in his book at the end of the day over seven days.

Pages Left to Read in Victor’s Book
On a coordinate plane, the x-axis is labeled Day and the y-axis is labeled Pages left. On day 0 there were 220 pages; Day 1, 180; Day 2, 170; Day 3, 140; Day 4, 140; Day 5, 100; Day 6, 60; Day 7, 40.

Which statement is supported by the graph?
Victor read 0 pages on day 4.
Victor read 170 pages on day 2.
Victor read the same number of pages on day 1 and on day 2.
Victor read the same number of pages on day 3 and on day 4.

To analyze the provided statements based on the graph of pages left to read, we can compare the numbers of pages left at the end of each day:

  • Day 0: 220 pages left
  • Day 1: 180 pages left
  • Day 2: 170 pages left
  • Day 3: 140 pages left
  • Day 4: 140 pages left
  • Day 5: 100 pages left
  • Day 6: 60 pages left
  • Day 7: 40 pages left

Now let's evaluate each statement:

  1. Victor read 0 pages on day 4.

    • Pages left on day 3: 140
    • Pages left on day 4: 140
    • This means Victor did not read any pages on day 4. (This statement is supported.)
  2. Victor read 170 pages on day 2.

    • This is not accurate; the number 170 indicates the pages left at the end of day 2. We cannot determine how many pages Victor read specifically on day 2 from this information alone. (This statement is not supported.)
  3. Victor read the same number of pages on day 1 and on day 2.

    • Pages left on day 1: 180
    • Pages left on day 2: 170
    • The difference implies Victor read more pages on day 1 than day 2. (This statement is not supported.)
  4. Victor read the same number of pages on day 3 and on day 4.

    • Pages left on day 3: 140
    • Pages left on day 4: 140
    • Since the number of pages left did not change from day 3 to day 4, Victor read 0 pages on each of those days. (This statement is supported as well.)

Based on this analysis, the statements supported by the graph are:

  • Victor read 0 pages on day 4.
  • Victor read the same number of pages on day 3 and on day 4.

Therefore, the first statement ("Victor read 0 pages on day 4.") is a clear and direct interpretation from the graph.
