# Math 10 week 17

this week in math ten we learnt about systems and how to find the system of two lines. A system is a point where two line cross on a graph. There are three different types of systems 1. There the normal system were we have two lines with different slopes 2. They are also parrelel systems where they have the same slope and there for have no points in common. 3. Coincident systems is the last one this is when we have two lines that are actually one on top of each other. In that case for a system like this there is no limit to how many solutions there are.

We we also learnt an easy way to find the solution to a system called substitution. By using substitution we can find the answer by inputting the coordinates we come up with to find our answer and verify it.
