A pair of linear equations in two variables ($x$ and $y$) can be represented as:
Where $a_1, b_1, c_1, a_2, b_2, c_2$ are real numbers and $a_1^2+b_1^2 \neq 0$, $a_2^2+b_2^2 \neq 0$.
Google loves structured data. This table contains the core conditions that get asked in 1-mark MCQs and case studies:
| Ratio Comparison | Graphical Representation | Algebraic Interpretation | Consistency |
|---|---|---|---|
| $\frac{a_1}{a_2} \neq \frac{b_1 |
