Liam named a point that is a solution and lies on the graph:
2(2) − 5(−1) = 4 + 5 = 9, so (2, −1) is on the graph.
Bella named a point that is not a solution and lies above the graph:
2(−2) − 5(1) = −9 < 9, and for x = −2 the graph has y = −13/5 = −2.6, so (−2,1) is above the graph.
Marco named a point that is not a solution and lies below the graph:
2(11) − 5(2) = 12 > 9, and for x = 11 the graph has y = 13/5 = 2.6, so (11,2) is below the graph.
2(2) − 5(−1) = 4 + 5 = 9, so (2, −1) is on the graph.
