y = \frac{5}{9} x

$y = \frac{5}{9} x$

Step 1

Combine

\frac{5}{9}

$\frac{5}{9}$ and

x

$x$ .

y = \frac{5 x}{9}

$y = \frac{5 x}{9}$

Step 2

Since the equation can be written in the form

y = k x

$y = k x$ ,

y

$y$ varies directly with

x

$x$ and

k

$k$ . The constant of variation,

k

$k$ , is

\frac{5}{9}

$\frac{5}{9}$ .

\frac{5}{9}
