We have the following:
Through the answer options we can observe the following.
option A.
the point (0,8) is not on the graph
option B
the point (8,0) is not on the graph
option C
the point (0,7) if it is in the graph, but the equation does not correspond, because if we replace we have:
7 * 0 - 4 * 7 = -28 and this is wrong.
Option D
the point (0.7) if it is on the graph and the equation if it corresponds to the graph.
the answer is the option D
