17 Mark this question A graph accompanying the question "Assuming ceteris paribus, what principle behind the law of demand is this graph illustrating?" The horizontal x-axis represents quantity and has 12 divisions. The vertical y-axis represents price, also with 12 divisions. Curve D starts roughly at x = 6.6 and ends roughly at y = 1.5. Points P1 and P2 are marked on Curve D. P1 is at x = 6 and y = 0.50. P2 is at x = 3 and y = 1.25 Assuming ceteris paribus, what principle behind the law of demand is this graph illustrating? Barring special circumstances, a decrease in price will have no effect on an increase or decrease in quantity. Barring special circumstances, an increase in price will always lead to a decrease in quantity. Barring special circumstances, an increase in price will always lead to an increase in quantity. Barring special circumstances, a decrease in price will always lead to a decrease in quantity
