Answer:
Step-by-step explanation:
The key to being able to identify correctly whether a relation is a function or not is to look at the x values. A relation is NOT a function if any x value is used more than once. In our graph, there are no repeats of any x value, so this relation is in fact a function.
Option B:
is the ratio used to convert to miles to feet.
Explanation:
Given that the distance is 1.7 miles
We need to convert the distance 1.7 miles to feet.
The ratio of miles to feet can be determined by finding how many feet are there in a mile.
There are 5280 feet in a mile.
To convert the miles to feet, we need to multiply the mile by 5280 feet.
Thus, the distance is given by

Hence, the distance of 1.7 miles to feet is 8976 feet.
Thus, the ratio that is required to convert miles to feet is 
Therefore, Option B is the correct answer.
