This is meant to determine which of the three ways we are studying to use when solving a system involving at least one non-linear equation.

|
|
|
|
|
|
|
|
|
|
Do the two equations have the exact same powers of either x or y?
|
YES
|
Use elimination!
|
| |
| |
| |
NO
|
|
|
|
|
|
|
|
|
|
Does ONE of the equations have just x or just y (no squares) in it?
|
YES
|
Use substitution!
|
| |
| |
| |
NO
|
|
|
|
|
|
|
|
|
|
Graph them, find the intersections
Remember to use both + and - if you have a root!
