@phi can you help me?

phi · Answer

linear means "line"
a system of two linear equations could correspond to two lines on a graph. the solution is where the lines cross.

phi · Answer

non-linear means not a line.
Think of curves that you plot that are not lines.
Can you think of any ?

anonymous · Answer

no

phi · Answer

Have you seen graphs of *anything* other than a line ?

anonymous · Answer

yes

phi · Answer

what ?

anonymous · Answer

well i don remember what they are called..

phi · Answer

parabolas?  circles?  hyperbolas?  ellipse?

anonymous · Answer

i've seen parabolas

phi · Answer

If we plot two parabolas that cross each other, that would be a "system of non-linear equations" .  The solution is where the intersect each other.


Perhaps the easiest "system" would be two parabolas, where one is concave up and the other is concave down, like this:
|dw:1423319113446:dw|
