Step-by-step explanation:

Answer:
The relation
or y = seven-halves x is a direct variation that contains the ordered pair (2,7).
Step-by-step explanation:
Given:
The ordered pair = (2, 7).
Now, to get the direct variation:
As (2,7) lies on it.
So, direct variation means 


Now,




Now, to get the direct variation:


or y = seven-halves x.
Therefore, the relation
or y = seven-halves x is a direct variation that contains the ordered pair (2,7).
