A) \[4x-3y-31=0\]
B) \[3x-4y-41=0\]
C) \[4x+3y-1=0\]
D) \[3x+4y+8=0\]
Correct Answer: A
Solution :
[a] \[3x+4y+5=0\] or \[y=\frac{-3}{4}x+\frac{-5}{4}\] Slope \[=\frac{-3}{4}\] Slope of required line, \[m=\frac{-1}{-\frac{3}{4}}=\frac{4}{3}\] Also line passes through \[(4,-5)\] Equation of line, \[y+5=\frac{4}{3}(x-4)\] \[\Rightarrow 3y+15=4x-16\] \[\Rightarrow 4x-3y-31=0\]You need to login to perform this action.
