The graph represents the journey of a bus from the bus stop to different locations:

part a: use complete sentences to describe the motion of the bus in parts 1, 2, 3, 4, and 5 of the journey. (4 points)

part b: in which parts of the graph is the function increasing, decreasing, and constant? (4 points)

part c: is the graph linear or non-linear? explain your answer. (2 points)

Step-by-step explanation:

A.

In part 1, the bus drives pretty linearly.

In part 2, the bus is at a stop.

In part 3, the bus drives much faster, as the slope is much larger.

In part 4, the bus is at a stop.

In part 5, the bus comes back to its starting point. 

B. The bus is increasing in parts 1 and 3, decreasing in part 5, and at a constant at parts 2 and 4. 

C. The graph is non-linear, as the slope is not at a constant.

Hope this helps

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
