Observe the graph, the two lines are intersect at point , so this point satisfy these two line equations.

Consider option A system of equations is .

The point substitute in the first equation, .

This is true.

The point substitute in the second equation, .

This is true.

So option A system of equation follow the graph solution.

Consider option B system of equations is .

The point substitute in the first equation, .

This is false, so the point is not solution of first equation, .

So option B system of equation is not follow the graph solution.

Consider option C system of equations is .

Already solved for the point is solution of first equation, .

The point substitute in the second equation, .

This is false, so the point is not solution of second equation, .

So option C system of equation is not follow the graph solution.

Consider option D system of equations is .

Already solved for the point is not a  solution of first equation, .

So the point is not solution of first equation, .

So option D system of equation is not follow the graph solution.

The option A system of equation only follow the graph solution.
