What to Focus On
- A single linear equation in two variables has many solutions.
- Two independent equations are needed for one unique solution.
- The Model method uses rectangles or portions of rectangles to represent unknowns.
- General form: ax + by + c = 0.
- At least one of a or b must be non-zero.
- The graph is a straight line.
- One equation with two unknowns gives many solutions.
- Two independent equations give one unique solution.
- A pair of equations is solved by finding the common solution.
Common Mistakes to Avoid
If a pair of equations has two variables, one equation is enough to find the answer.
Consistent always means one solution only.
Inconsistent and dependent mean the same thing.
