Question

Which graph below shows a system of equations with infinitely many solutions?

Answer 1

the solutions are the points where the two lines intercept,

if the lines never meet, there are no solutions,

if the lines cross an one point, where there cross is the single solution

if the lines are overlain, there are an infinite number of point that appear on both lines simultaneously, ie infinite solution

Answer 2

NB: a system with infinite solutions, does not mean that every point is a solution

Answer 3

So it would be C?
