Which statement is correct about the graph of (10x+15y=35) and (2x+3y=9)?

Answer and explanation

Correct answer: Lines are distinct parallel

For the two equations, \\(a_1/a_2=10/2=5\\) and \\(b_1/b_2=15/3=5\\), but \\(c_1/c_2=35/9\\). Thus, \\(a_1/a_2=b_1/b_2\\ne c_1/c_2\\), so the two lines are distinct and parallel. They neither intersect nor coincide. Exam tip: the condition \\(a_1/a_2=b_1/b_2\\ne c_1/c_2\\) represents distinct parallel lines.
