Point (20, 5) is on the graph of inverse variation. Which of the following ordered pair is on the graph?.

Bess [88]

The point $(10, 10)$ is on the graph.

<h3>Procedure - Inverse variation</h3><h3 /><h3>Inverse variation model</h3><h3 />

An <em>inverse</em> variation is represented by the following formula:

$y = \frac{k}{x}$ (1)

Where:

$x$ - Independent variable.
$y$ - Dependent variable.
$k$ - Proportionality constant.

We can eliminate the proportionality constant by creating the following relationship:

$x_{1}\cdot y_{1} = x_{2}\cdot y_{2}$ (2)

<h3>Determination of another point</h3>

If we know that $x_{1} = 20$ , $y_{1} = 5$ and $x_{2} = 10$ , then the remaining variable is:

$y_{2} = \left(\frac{x_{1}}{x_{2}} \right)\cdot y_{1}$

$y_{2} = \left(\frac{20}{10} \right)\cdot (5)$

$y_{2} = 10$

The point $(10, 10)$ is on the graph. (Correct choice: C) $\blacksquare$
