Answer 1

Inversely related.

xy=84

Graph B

Explanation:

Here we can clearly observe that as value of x increases the value of y decreases . So x and y are inversely related.

Let the relation between y and x be
`y=(c)/(x)`

ie.
`xy=c`

Now substitute value to find the value of c.

x=2,y=42

`c=2*42=84`

Therefore the relation between x and y is
`xy=84`

we can check for other points it satisfies .

We know that the graph for the above relation is upward parabola which is depicted in Graph B.
