What is solution to a system of equations?

• A point that satisfies neither equation

• A point that satisfies only one equation

• You can never find a solution to a system of equations

• The point that satisfies both equations.

A system of equations can have:

• 1 solution, the point of intersection

• No solution, parallel lines

• Infinite solutions, overlapping lines

• All of the above!
