State the position of the lines for (2x-3y=5) and (4x-6y=7).

Answer and explanation

Correct answer: Distinct parallel lines

Comparing the coefficients, \(a_1/a_2=2/4=1/2\) and \(b_1/b_2=(-3)/(-6)=1/2\), but \(c_1/c_2=5/7\). Thus, \(a_1/a_2=b_1/b_2\ne c_1/c_2\), which is the condition for distinct parallel lines. Therefore, option C is correct. Option B is incorrect because coincident lines require all three ratios to be equal. Exam tip: If \(a_1/a_2=b_1/b_2\ne c_1/c_2\), the lines are distinct and parallel.
