Which set of ordered pairs represents y as a function of x?

Question 1 options:

{(1, 2), (2, -3), (3, 4), (4, -5)}

{(2, 3), (3, 5), (3, -5), (-2, 8), (-2, -8)

{(1, 2), (2, 3), (3, 4), (3, 5)}

{(1, 3), (1, 5), (1, 7), (1, 9), (1, 11)}

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
