Tell whether the equation represents a direct variation. If so identify the constant of variation. 2x + 3y = 0

OpenStudy (kinggeorge):

First, solve for y. \[2x+3y=0 \longrightarrow 3y=-2x \longrightarrow y=-{2\over3}x\]Can you tell me what the answer to your question is from here?

OpenStudy (kinggeorge):

It is in fact a direct variation. Can you also find the constant?
