Mathematics: Which outcome is not possible for the graph of a system of two linear equations? a the lines intersect at one point so the system has one solution. b the lines intersect in two different points so the system has two solutions. cthe equations graph the same line, so there are infinite solutions. d the lines do not intersect so there are no solutions.

B The lines intersect in two different points so the system has two solutions.

Step-by-step explanation:

The two lines can never intersect each other at two points. Two lines intersects only once if they intersect otherwise they are parallel or coincide.

Thus the only not possible outcome for the system of two linear equations is B. The lines intersect in two different points so the system has two solutions.
