1. 7.4 Consistent and Inconsistent Systems pg. 338 to 344
So far you have learned how to solve systems of equations by:
1. Graphing
2. Substitution
3. Elimination
YOU ARE STILL DOING THIS FIRST!
NOW--you get to pick the method you want to solve with
AND--you have to classify the system by a name:
Inconsistent---(NO answer-cancels itself out, lines are parallel)
Consistent and independant---(ONE answer)
(This is what you have been doing)
Consistent and dependant ( SAME exact equations/lines)
