Is the point (4,7) on the graph of the linear equation below? Justify your answer. 4x + y = 28
The point (4, 7) is not on the graph. This is because 4 (4) +7(7) # 28.
The point (4, 7) is on the graph. This is because 4 () + 7 (1) = 28.
O The point (4, 7) is not on the graph. This is because 4 (7)+7(4) # 28.
The point (4, 7) is on the graph. This is because in the equation Ax + By = C, A = 4 and B = 7.
