no.
Direct
The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. The formula for direct variation is. y=kx (or y=kx ) where k is the constant of variation .

if the line runs through the origin it is a direct variation no matter if it is increasing or decreasing
