I'm pretty sure it might be Never..

If you're talking about linear equations, then they will only intersect more than once only if you have a dependent system. So this happens some of the time but not all the time.


Ex: 

2x+3y = 6
4x+6y = 12

is a dependent system that has an infinite number of intersections

the answer is sometimes

Now I'm really confused. ._.

jim_thompson5910 · Answer

The lines 2x+3y = 6 and 4x+6y = 12 lie on top of one another (since they're the same line). So they intersect at an infinite number of points.

OH. I see what you mean. n.n Thanks.

jim_thompson5910 · Answer

That's just one example of a system that has more than one intersection
