01 / QUICK RECAP
Connect the ideas.
- Keep equations balanced and check the original statements.
- A simultaneous solution satisfies both equations and is a common graph point.
- Parallel distinct lines have no solution; coincident lines have infinitely many.
- Reverse an inequality when multiplying or dividing by a negative.
- Use boundary style, test points and overlapping half-planes for two-variable inequalities.
- Apply practical domains such as nonnegative integer counts.
