The distance of a point (2,5) from the line 3 x+y+4=0 measured along the line L ₁ and L ₂ are same. If slope of line L₁ is 3 4 , then slope of the line L ₂ is
Options
- A-3 4
- B1 3
- C1 4
- D0
Correct answer
D. 0
Step-by-step solution
According to the given condition, in ABC , AB = AC . ABC is an isosceles triangle. Let m , m ₁, ~m ₂ be the slopes of given line, L ₁ and L ₂ respectively. array ll & m =-3, ~m ₁= 3 4 & | m - m ₁ 1+ mm ₁ |= | m - m ₂ 1+ mm ₂ | & 3= | -3- m ₂ 1+3 ~m ₂ | & m ₂=0 array
