If y varies directly as x, and the constant of variation is -6, which equation represents the relationship?

• y = 6x

• y = - 6x

• y = -6 / x

• y = x / -6

If the point (3,6) lies on the graph of an inverse variation, which represents the inverse variation equation?

• y = 6x

• y= 18x

• y = -6/x

• y= 18/x

• 1/5

• 5

• 45
