If the equation C = 20 + 0.6Y, where C is consumption and Y is disposable income, were graphed, Group of answer choices the vertical intercept would be +0.6 and the slope would be +20 At zero disposable income consumption would be +20 and the MPC would be +0.6 it would reveal an inverse relationship between consumption and disposable income. the vertical intercept would be negative, but consumption would increase as disposable income rises
