Answer:
A - one
Step-by-step explanation:
A typical demand curve, in economics, depicts the relationship between price of a commodity on the y-axis, and quantity demanded on the x-axis.
The demand curve obeys the Law of Demand, which states that the higher the price, the lower the quantity demanded of that commodity, and vice versa, all things being equal. Thus, a typical demand curve will slope downwards, from left to the right.
Therefore, line 1 indicates the demand curve.
-4 - 1 = -5 can be an equation that equals -5.
