Special Cases for Systems of Linear Equations

So far in this chapter, we have been dealing with systems of equations that intersect at exactly one point. There are situations, however, that do not result in one intersection point. Sometimes, the lines are parallel, meaning there are no points of intersection. These equations result in a false statement when you try to solve them (like 4 = 0 ). Sometimes, you will get a true statement (like 0 = 0), and this indicates that the lines are coincidental, or lie on top of each other. These lines have an infinite number of common points.
