Answer: A. One
Explanation:
In the given graph , it can be seen that the two lines are intersecting each other at a particular point.
We know that when two lines intersect each other , then the intersection point represents the solution to the system.
Since the two lines can intersect only once on a Cartesian plane.
Then , the number of solutions to the given system of equations = One
Hence, there are only one solution to the given system.
