Systems of Equations
Solve a System of Equations by Graphing
To solve a system of equations by Graphing:
1) Graph both equations
2) Find the point where both equations meet
1.)
y = x + 2
y = 3x ­ 2
2.)
­2x + y = 2
y = ­3x + 2

A system of equations that has at least one solution is consistent.
A consistent system that is independent exactly one solution.
A consistent system that is dependent has infinitely many solutions.
A system of equations that has no solution is inconsistent.
­Tell whether each graph has one solution, no solution or infinitely many solutions .
­Tell whether they are consistent, inconsistent, independent or dependent.
