SYSTEM of linear equations (inequalities) – a set of two or more linear equations (inequalities) “Any ordered pair that is a solution to EACH equation (inequality) in the system is a solution to the system. NOTES and EXAMPLES ***To solve a system of linear equations: 1. Graph each equation on the same coordinate plane…using ANY graphing method. (Be as accurate as possible when drawing lines!) 2. Find the solution by looking for the intersection point(s). 3. Check your solution by substituting back into all equations in system. So…here is what can happen: 1) One solution – from one point of intersection 2) Many (infinite) solutions – lines are the same line 3) No solution – lines are parallel and do not intersect
