Question

Identify the graph representing indirect variation.

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

For an indirect variation, as $x$ approaches $0$, $y$ becomes very large, i.e., with increasing value of $x$, $y$ decreases and vice versa.

This type of relation can be represented by a curved graph like the one in the option (c.).



Option (a.) which is also a curved graph, in the initial part, shows increase of $y$ with $x$ which is a kind of direct variation. But towards the end, $y$ decreases with increasing $x$, showing indirect relation.
However, this graph cannot be classified as an indirect variation.


Options (b.) and (d.) have straight line graphs, so they are incorrect.
