Systems
of Equations: Graphing
Here are the two systems we
just saw solved by graphing:
If
the equations were all in slope-intercept form, we would be able to see the outcomes
much faster.
Same slope,
different intercept.
The lines
must be parallel.
The system
has no solution.
The system
is inconsistent.
Same slope,
same intercept.
The lines must
coincide.
The system
has infinitely many solutions.
The system is
dependent.
