a
y+3x=0
b
x+3y=0
c
y-3x=0
d
x-3y=0
detailed solution
Correct option is C
Let the required line meet the given lines at α1,β1 and α2,β2 respectively.then α1−β1,+2=0, α2+β2+4=0Also α1+α22=0, β1+β22=0⇒ α2=−1,β2=−3 and α1=1,β1=3Equation of the line passing through (1, 3) and (0, 0) is y=3x ⇒ y-3x=0Talk to our academic expert!
