Two straight paths are represented by the equations x – 3y = 2 and –2x + 6y = 5.Check whether the paths cross each other or not. |

Answer» Given linear equations are x – 3y – 2 = 0 …(i) -2x + 6y – 5 = 0 …(ii) On comparing with ax + by c=0, We get a1 =1, b1 =-3, c1 =- 2; a2 = -2, b2 =6, c2 =- 5; a1/a2 = – ½ b1/b2 = – 3/6 = – ½ c1/c2 = 2/5 i.e., a1/a2 = b1/b2 ≠ c1/c2 [parallel lines] Hence, two straight paths represented by the given equations never cross each other, because they are parallel to each other. |
