The point (1, 3) on the graph typically represents the coordinates where the first value corresponds to the x-axis and the second value corresponds to the y-axis. In this case, it indicates that for 1 level (the x-coordinate), Sonia completes 3 puzzles (the y-coordinate).
Therefore, the correct interpretation of the point (1, 3) is:
A. Sonia completes 1 puzzle every 3 levels.
This option represents the ratio of puzzles completed over levels, with 1 level corresponding to 3 puzzles.
Please be aware that if you meant to connect this scenario with the correct options available related to the point (1, 3) regarding the actual understanding of information, then:
The correct answer would be B. Sonia completes 3 puzzles on each level.
Since the x-axis typically represents the level and the y-axis the puzzles completed in that level, so 1 level corresponds to 3 puzzles here.
