The Relationship between money earned and hours worked Is linear. Joe computers the slow between (4, 30) and (12, 90), Then computer is the slow between (4, 30) and (10, 75). How do the two slopes compare?

the answer would be  

a.

3: 1

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.
