Part b
which graph represents the system?

a. the graph with x-coordinate marks 0, 2, 4, 6, 8, 10, and 12; y-coordinate marks 0, 2, 4, 6, and 8. the x-axis represents number of postcard books and y-axis represents number of magnets. there are two lines which intersect each other at (4, 5). the first line starts from (0, 7.5) and ends at (12, 0). the second line starts from (0, 9) and ends at (9, 0). there is region which is shaded below the intersection point and between two lines.
b. the graph with x-coordinate marks 0, 2, 4, 6, 8, 10, and 12; y-coordinate marks 0, 2, 4, 6, and 8. the x-axis represents number of postcard books and y-axis represents number of magnets. there are two lines which intersect each other at (1.5, 6.5). the first line starts from (0, 7.5) and ends at (7, 3). the second line starts from (0, 8) and ends at (8, 0). there is region which is shaded below the intersection point and between two lines.
c. the graph with x-coordinate marks 0, 2, 4, 6, 8, 10, and 12; y-coordinate marks 0, 2, 4, 6, and 8. the x-axis represents number of postcard books and y-axis represents number of magnets. there are two lines which intersect each other at (1, 7). the first line starts from (0, 7.5) and ends at (12, 0). the second line starts from (0, 8) and ends at (8, 0). there is region which is shaded below the intersection point and between two lines.
d. the graph with x-coordinate marks 0, 2, 4, 6, 8, 10, and 12; y-coordinate marks 0, 2, 4, 6, and 8. the x-axis represents number of postcard books and y-axis represents number of magnets. there are two lines which intersect each other at (3, 3.5). the first line starts from (0, 6.5) and ends at (5, 1.5). the second line starts from (0, 1.5) and ends at (5.5, 5.5). there is region which is shaded to the left of the intersection point and between two lines.
