Which equation represents a proportional relationship? y=−2x y=32x y = 4x + 3 y=2(x+1)

Answer:Option B is correct.y =32x represents a proportional relationship.Step-by-step explanation:If two quantities are said to have a proportional relationship if they vary in such a way that one of the quantities is a constant multiple of the other i.e,y = |k| y where |k| is constant proportionality.By definition :y =32x  where k =32 is constant ,  represents a proportional relationship.
