Question

on shifting the origin to a point p, the axes remaining parallel to the original axes,the equation ax+by+c=0 is transferred to ax+by+c=0.show that the locus of p is the straight line ax+by=k​

Answer 1

Given line

ax+by+c=0 but a=0

by+c=0

Equation of line perpendicular to above line be

bx+λ=0

x=−

b

λ

In the option only y−axis:x=0 is same to required equation

Hence option B is correct
