Question

For a + b + c = 0, the line 3ax + 4by + c = 0 passes through    the fixed point …….

(a) [(1/3), – (1/4)]

(b) [– (1/3), (1/4)]

(c) [(1/3), (1/4)]

(d) [– (1/3), – (1/4)]

Answer 1

The correct option (c) [(1/3), (1/4)]   

Explanation:

line : 3ax + 4by + c = 0

for option C, i.e. (x, y) = [(1/3), (1/4)] point satisfier given equation. 

hence line passes through [(1/3), (1/4)]
