This is not a maths exam! It is of no relevant what the sign of 'b' is. The price is always equal to a - bQ. Ignore the sign of b. Do watch my free lectures on this. Then it should be obvious that for a higher Q, then the price must always be lower. It is no good just learning rules - only 50% of the exam involves calculations. The rest of it is testing that you understand what is happening :-)
