$k = \frac{3}{2}$ $k=3/2$

Explanation:

$a direct variation equation has the form$ $"a direct variation equation has the form"$

$y = k x where k is the constant of variation$ $y=kx" where k is the constant of variation"$

$- 3 x + 2 y = 0 can be expressed in this form$ $-3x+2y=0" can be expressed in this form"$

$\Rightarrow 2 y = 3 x \Rightarrow y = \frac{3}{2} x$ $rArr2y=3xrArry=3/2x$

$y = \frac{3}{2} x is a direct variation equation with k = \frac{3}{2}$ $y=3/2x" is a direct variation equation with "k=3/2$
