The graph shows the relationship between the number of passing drills and running drills Coach Owens has his players complete for practice. Write an equation to represent the graph Then, find a possible solution.

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
