Answer: A) 2, 7, 9
<u>Step-by-step explanation:</u>
In a sudoku puzzle, there are three rules:
- Each vertical line must contain the numbers 1 - 9, with no duplicates
- Each horizontal line must contain the numbers 1 - 9, with no duplicates
- Each 3 x 3 box must contain the numbers 1 - 9, with no duplicates.
Using logic:
2 must go in the 1st box. It cannot go in the 2nd or 3rd shaded square because 2 is already in that 3 x 3 box.
That leaves the 2nd and 3rd shaded square.
9 cannot go in the 2nd shaded square because 9 is already in that vertical line.
Therefore, 9 must go in the 3rd shaded square.
That leaves the 2nd shaded square.
7 must go in the 2nd shaded square because it is the only number remaining (2 and 9 have already been placed in the other squares).
If we find the unit rate for the graph, that means it's proportional. For the first question, we could see that the unit rate is 2/1, so it's proportional.
