A) \[x+y=1\]
B) \[x-y=1\]
C) \[x+y+1=0\]
D) \[x-y-2=0\]
Correct Answer: C
Solution :
The equation of line which cuts off equal intercepts from axes a (say) is \[\frac{x}{a}+\frac{y}{a}=1\]or \[x+y=a\] But it is passes through (1, -2), therefore \[1-2=a\] \[\Rightarrow a=-1\]. Hence the equation of straight line is \[x+y+1=0\].You need to login to perform this action.
