TS EAMCET · Maths · Straight Lines
A straight line makes an intercept on the \(Y\)-axis twice as long as that on \(X\)-axis and is at unit distance from the origin. Then the line is represented by the equations
- A \(2 x+3 y= \pm \sqrt{5}\)
- B \(x+y= \pm 2\)
- C \(x+y= \pm 2\)
- D \(2 x+y= \pm \sqrt{5}\)
Answer & Solution
Correct Answer
(D) \(2 x+y= \pm \sqrt{5}\)
Step-by-step Solution
Detailed explanation
Let equation of line be \( \frac{x}{a}+\frac{y}{2 a}=1 \) \(\Rightarrow \quad 2 x+y=2 a\) Distance from origin is…
