Answer:
The correct option is 1.
Step-by-step explanation:
If a system of equations have two equation of lines. Then the intersection point of both lines is the solution of given system of equations.
The given graph contains two lines. All the points lie on the line are the solution of that line.
From the given graph it is clear that both the line intersect each other at point (1,1). It means both lines passes through the point (1,1). So, (1,1) is the solution of system of equations.
Since (1, 1) is the solution to both lines K and J. Therefore the correct option is 1.
