For a pair of linear equations in two variables, if \(\frac{a_1}{a_2}=\frac{b_1}{b_2}\ne\frac{c_1}{c_2}\), what is the position of their lines?

Answer and explanation

Correct answer: They are distinct parallel lines

When \(a_1/a_2=b_1/b_2\), the two lines have the same slope. Since \(c_1/c_2\) is different, they cannot be the same line; hence they are distinct parallel lines with no solution. Exam tip: equal first two ratios and an unequal third ratio indicate an inconsistent pair.
