Step-by-step explanation:
Answer:

Step-by-step explanation:
Given
See attachment for number line
Required
Determine the model
From the attachment, we can see that each partition is 1/3
The gray rectangle covers 11 partitions.
So:


Express as a mixed number

The black rectangle covers 8 partitions
So:


Express as a mixed number

So, the model is:

Where Total is the point where the black rectangle stops

Point c is quadrant 2,point T is quadrant 1,point R is x axis , point h is quadrant 3
Answer:
y = x - 8
Step-by-step explanation:
7/7X - 8
the y intercept was the only tricky part
1km=1000 meters so 2km=2000, and if you have 4 of the races you multiply 4 by 2000 which gives you 8000 meters
4*2000=8000
