Question

The straight line ax+by+c=0 where 3a+2b+4c=0 are concurrent the point

Answer 1

Dear student
3a+2b+4c = 0
Dividing the equation by 4

3a/4+2b/4+4c/4 = 0
=> 3a/4 + b/2+c = 0
x = ¾ and y = ½ satisfied this relation

Hence the set of lines are concurrent at (3/4, ½)

Answer 2

Dear student

3a+2b+4c = 0

Dividing the equation by 4

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

=> 3a/4 + b/2+c = 0

x = ¾ and y = ½ satisfied this relation

Hence the set of lines are concurrent at (3/4, ½)
