If the lines joining the origin to the points of intersection of a line \(\mathrm{L}\) and \(\mathrm{x}^2+\mathrm{y}^2=4\) are the coordinate axes, then the equation of the line \(\mathrm{L}\) is
- A \(x+y=2\)
- B \(x+y=4\)
- C \(x+y=1\)
- D \(x+y=0\)
Answer & Solution
Correct Answer
(A) \(x+y=2\)
Step-by-step Solution
Detailed explanation
\(\because x^2+y^2=4 \Rightarrow x^2+y^2=2^2\) \(\therefore\) Radius \(\mathrm{r}=2\) So, the coordinate of the point \(\mathrm{A}\) and \(\mathrm{B}\) are \((2,0)\) and \((0,2)\) respectively. Then the equation of the required line is…
