Which relation is a direct variation that contains the ordered pair (2, 7)? y = 4x – 1 y = startfraction 7 over x endfraction y = two-sevenths x y = seven-halves x

The relation or y = seven-halves x  is direct variation.

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 direct variation.
