(0, 9)

(3, 14)
(2, 13)
Answer by ReadingBoosters(3246)   (Show Source):
You can put this solution on YOUR website! Using
f(x) = 2x + 9
...
Substitute each x value from the pair and confirm which y is not given.
...
2(0) + 9 = 9: (0,9) Good
2(7) + 9 = 14+9 = 23: (7,23) Good
2(3) + 9 = 6+9=15: (3,15) Oops, (3,14) is not an ordered pair!
2(2) + 9 = 4+9=13: (2,13) Good
