Best answer as selected by question asker.
Your equation of line is
Sustitute respectively y and x are 0 ,to get x and y interceps.
y=0 , `x=a/b`
Area of triangle formed by line and axes
This implies b,2a,c are geometric progression
Appropriate answer be B
D is ruled out because condition a,b,c are of the same sign.
