To find the correct set of ordered pairs representing the number of friends and the total cost for seeing the movie, we can calculate the total cost based on the number of friends attending. The cost per person is $7.

The total cost (y) for x friends is calculated as follows:

  • For 2 friends: \( y = 2 \times 7 = 14 \)
  • For 3 friends: \( y = 3 \times 7 = 21 \)
  • For 4 friends: \( y = 4 \times 7 = 28 \)
  • For 5 friends: \( y = 5 \times 7 = 35 \)

Thus, the ordered pairs representing this relationship are:

  • (2, 14)
  • (3, 21)
  • (4, 28)
  • (5, 35)

Now, looking at the options provided:

  1. (2, 9), (3, 10), (4, 11), (5, 12)
  2. (14, 2), (21, 3), (28, 4), (35, 5)
  3. (2, 14), (3, 21), (4, 28), (5, 35)
  4. (9, 2), (10, 3), (11, 4), (12, 5)

The correct answer is: (2, 14), (3, 21), (4, 28), (5, 35).
