Find the Constant of Variation 4y=5x

$4 y = 5 x$

Step 1

Divide each term in $4 y = 5 x$ by $4$ and simplify.

Divide each term in $4 y = 5 x$ by $4$ .

$\frac{4 y}{4} = \frac{5 x}{4}$

Simplify the left side.

Cancel the common factor of $4$ .

Cancel the common factor.

$\frac{4 y}{4} = \frac{5 x}{4}$

Divide $y$ by $1$ .

$y = \frac{5 x}{4}$

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 $\frac{5}{4}$ .

$\frac{5}{4}$
