We can derive a demand curve by repeatedly changing the price of x, _____________ Group of answer choices rotating the budget constraint then mapping out the new optimal quantities of x and y consumed. Finally, on a separate graph, map out the price of x and optimal quantity of x consumed. rotating the budget constraint then mapping out the new optimal quantities of x and y consumed. Finally, on a separate graph, map out the optimal quantity of x and optimal quantity of y consumed. shifting the budget constraint then mapping out the new optimal quantities of x and y consumed. Finally, on a separate graph, map out the optimal quantity of x and optimal quantity of y consumed. shifting the budget constraint then mapping out the new optimal quantities of x and y consumed. Finally, on a separate graph, map out the price of x and optimal quantity of x consu
