Answer:
On a coordinate plane, x-axis is numbered negative 5 to positive 5 in increments of 1, and the y-axis is numbered negative 27.5 to 27.5 in increments of 5.5. Solid circles appear at points (0, 0), (1, 5.5), (2, 11), (3, 16.5), (4, 22), (5, 27.5)
Step-by-step explanation:
The first graph is not correct because you cannot sell or buy, for example 1.1, cans of tomato.
The second graph is correct because x is discrete variable, that is, it only take values like 1, 2, 3, etc.
The third and fourth graphs are not correct because you cannot sell or buy negative cans of tomatoes.
