Find the Constant of Variation 2y=x

$2 y = x$

Step 1

Divide each term in $2 y = x$ by $2$ and simplify.

Divide each term in $2 y = x$ by $2$ .

$\frac{2 y}{2} = \frac{x}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} = \frac{x}{2}$

Divide $y$ by $1$ .

$y = \frac{x}{2}$

Step 2

Since the equation can be written in the form $y = k x$ , $y$ varies directly with $x$ and $k$ . The constant of variation, $k$ , is $\frac{1}{2}$ .

$\frac{1}{2}$
