Yes, the equation represents direct variation. The constant is
Explanation:
In order to determine whether or not the given equation exhibits direct variation, you must first isolate for
Thus,
#8x+2y=0#
#2y=-8x#
#y=-4x#
Recall that the equation is technically,
#y=color(blue)(-4)xcolor(white)(i)color(red)(+0)#
In your case, since
Furthermore, the constant is the value of
