Answer:
The best estimate for the solution is the ordered pair 
Step-by-step explanation:
we have
------> equation A
------> equation B
we know that
using a graphing tool, the solution of the system of equations is the intersection point both graphs
The intersection point is 
therefore
The best estimate for the solution is the ordered pair
