Answer:

direct

Step-by-step explanation:

The standard form of an equation representing direct variation is

y = kx ← k is the constant of variation

The standard form of an equation representing inverse variation is

y = $\frac{k}{x}$ ← k is the constant of variation

y = - $\frac{2}{5}$ x ← represents direct variation with k = - $\frac{2}{5}$
