Question

Which of these graphs show that the linear system 3x+2y=12 and 6x+4y=24 has an infinite number solutions?

Answer 1

None of these graphs show that the linear system 3x+2y=12 and 6x+4y=24 has an infinite number of solutions because they do not intersect at a single point. The graphs either intersect at one point (a unique solution), are parallel (no solution), or are the same line (infinite solutions).
