A) \[2x+y=4\]
B) \[2x+y+4=0\]
C) \[2x-y=4\]
D) \[2x-y+4=0\]
Correct Answer: A
Solution :
Let the intercept be\[a\,\text{ and}\,2a\] , then the equation of line is \[\frac{x}{a}+\frac{y}{2a}=1\], but it also passes through (1, 2), therefore \[a=2\]. Hence the required equation is\[2x+y=4\].You need to login to perform this action.
