Answer:
Zero
C is the correct option.
Step-by-step explanation:
In the given graph, the given lines are parallel to each other and hence never intersect.
Now, we know that the intersection point (s) of two curves gives us the solution.
Here the lines are parallel to each other and hence do not intersect each other.
Thus, there would not be any intersection point.
Hence, the system of equations has no solution.
C is the correct option.
