1. If a system has exactly one solution, the system is blank and blank.
2. A system is an inconsistent system if the graphs are two blank lines.
3. if the graphs of the system are two lines that coincide, then the system is blank and blank.
4. Consistent and inconsistent systems are both blank.
5. If the slopes of the lines in the system are equal and their y-intercepts and also equal, then the system is blank and blank.
6. If the slope of the lines in the system are equal and their y-intercepts are also equal, then the system is blank and blank.
