Question

If there is no solution to a graph of a system of equations, then the lines must be?

Answer 1

If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. ... So when the graphs of two equations cross, the point of intersection lies on both lines, meaning that it is a possible solution for both equations.

Answer 2

If there is no solution, then the lines are

$\huge{\mathfrak{\boxed{Parallel}}}$
