See the picture below. Thanks to you all good people.

Consider the intertemporal budget constraint in the context of the two-period life-cycle model. When there is no tax on interest income, the slope of the intertemporal budget constraint is -1.4. Then the government imposes a 40 percent tax on interest income. Under this new tax rule, no deduction is allowed for interest payments. What is the slope of the new intertemporal budget constraint? Fill in the blanks below to indicate the slope of the intertemporal budget constraint to the left of the endowment point and to the right of the endowment point after the new tax rule is in place. Your numeric answer should be rounded to 2 decimal places. If your answer is negative, use a minus sign. If your answer is positive, do not use a plus sign. The new slope is to the left of the endowment point and to the right of the endowment point
