Systems of Linear Equations.

You can solve Systems of Linear Equations by Graphing and finding the Intersections.

A System of Linear Equations can have 1 solution - no solutions - or infinitely many solutions (Depending on how many times they intersect).

Different types of solutions

1. One solution: The solution is where the points intersect

2. No solution: The lines will never intersect so this system does not have an answer

3. Infinite solutions: The lines have the same equation.

Read Directions Carefully.

Sometimes you may be asked for only one of the variables in the solution or you could be asked for the # of solutions or the actual solutions.

Be sure to read the question carefully, so that you understand what you are being asked to do.
