Solving Systems by Graphing or Substitution.
... System of Equations • A system of equations is a collection of equations in the same variables. • The solution of a system of two linear equations in x and y is any ordered pair, (x, y), that satisfies both equations. The solution (x, y) is also the point of intersection for the graphs of the lines ...

The Discriminant
... (roots) you will get. The discriminant can be +, –, or 0 which actually tells you a lot! Since the discriminant is under a radical, think about what it means if you have a positive or negative number or 0 under the radical. ...
