Answer:
A. Zero.
Explanation:
We have been given an image of two parallel lines. We are asked to find the number of solutions for our given line.
We know that the solution of a system of equations is the point, where both lines intersect.
We also know that slope of parallel lines is equal, so they never intersect.
Since parallel lines never intersect, therefore, there is no solution for our given system of equations and option A is the correct choice.
