-$y = 4$ when $x = 14$
A) $y = x - 10$
B) $y = 2 x$
C) $y = \frac { 2 } { 7 } x$
D) $y = \frac { 7 } { 2 } x$

The direct variation equation is of the form $y = kx$, where $k$ is the constant of variation. Given $y = 4$ when $x = 14$, we find $k = \frac{4}{14} = \frac{2}{7}$. Thus, the equation is $y = \frac{2}{7}x$.
