Question

The three lines 3x + 4y + 6 = 0 and $\sqrt { 2 }$ x + $2 \sqrt { 2 }$= 0 and 4x + 7y + 8 = 0 are

• A. Sides of a triangle
• B. Concurrent
• C. Parallel
• D. None of these

Answer 1

Answer: (B)

Concurrent

Answer 2

Solving 3x + 4y + 6 = 0

4x + 7y + 8 = 0

x = –2, y = 0

which satisfies $\sqrt { 3 }$y + 2$\sqrt { 2 }$= 0 so concurrent.
