Write the slope intercept form of the equation of each line.

9) y = -x + 5

10) y = -7/2x - 5

11) y = x - 1

12) y = -5x/3 - 3

13) y = -4x/1

I'm not 100% sure for some of these answers since the pic is a bit blurry, but they're pretty accurate.

step-by-step explanation:

basically 2/5.

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.
