Answer:

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

Explanation:

Given:

The ordered pair = (2, 7).

Now, to get the direct variation:

As (2,7) lies on it.

So, direct variation means
y=kx.


x=2.


y=7.

Now,


y=kx


7=k* 2


(7)/(2) =k


k=(7)/(2)

Now, to get the direct variation:


y=kx


y=(7)/(2)x


y=(7)/(2)x or y = seven-halves x.

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