If `a ,b ,c` are variables such that `3a+2b+4c=0` , then show that the family of lines givenby `a x+b y+c=0` pass through a fixed point. Also, find that point.

Explanation

Given,

`3a+2b+4c=0`

So, it can be written as,

`=>2b=-3a-4c`

`=>b=(−4c−3a)/2​`

Putting in `ax+by+c=0`we get,


`=>ax+((−4c−3a)/2​)y+c=0`
