Find the Constant of Variation xy=7

$x y = 7$

Step 1

Divide each term in $x y = 7$ by $x$ and simplify.

Divide each term in $x y = 7$ by $x$ .

$\frac{x y}{x} = \frac{7}{x}$

Simplify the left side.

Cancel the common factor of $x$ .

Cancel the common factor.

$\frac{x y}{x} = \frac{7}{x}$

Divide $y$ by $1$ .

$y = \frac{7}{x}$

Step 2

The given equation $y = \frac{7}{x}$ can not be written as $y = k x$ , so $y$ doesn\'t vary directly with $x$ .

$y$ doesn\'t vary directly with $x$
