1. Is (3, -1) a solution to the system?

Answer:
No
Step-by-step explanation:
To find point (3, -1), begin at the origin. Move 3 units to the right, then 1 unit down.
Neither of the lines go through the point (3, -1)
Answer:
No
Step-by-step explanation:
No, (3, -1) is not a solution to the system. Because, lines are not intersecting at this point.
Actually, both the lines are going parallel to each other. Hence, there will be no solution.
