The amount of time required to download a song from Michael's computer to his music player is the same for each song he
downloads.
A linear model of this situation contains the values (130, 104) and (205, 164), where x represents the number of songs he
wants to download to his music player, and y represents the total amount of time, in minutes, it will take him to download the
Songs.
What is the rate of change in this linear model?
A. 0.8 of a minute per song
B. 75 minutes per song
C. 0.4 of a minute per song
OD. 1.6 minutes per song

i would pic false cause it goes down towards negative

step-by-step explanation:

50-38=12

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
