Debbie ran four time trials. first she ran 2/6 of a mile. then on each of the next three trials she ran 2/6 of a mile from her previous distance. draw a model or number line to represent one of debbie’s runs.

The number line which represents Debbie's run is shown in number line below.

Step-by-step explanation:

Consider a number line in which each interval is of 1 mile.

Since the denominator of given fraction is 6 .Mark 5 points between 0 and 1 , so that the 6 th point will be 1.

Then mark first interval 0 to 2nd point which shows she run 2/6 of a mile.

Similarly mark second interval 2nd to 4th point and third interval 4th to 6th point which is ultimately the 1 mile point and each interval is of 2/6 of mile.

[because each interval has 2 points out of 6 points]

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
