Answer:
B
Step-by-step explanation:
When an ordered pair is a solution to a system of equations in two variables, it must mean that when you plug in the ordered pair into both equations, it must come out true (this is literally the definition of a solution to a system of equation). Technically, A is also facts, but B is a "more inclusive" facts so that's your answer. Hope this helps! :)
