TS EAMCET · Maths · Straight Lines
The equation of a straight line passing through the point \((1,2)\) and inclined at \(45^{\circ}\) to the line \(y=2 x+1\) is
- A \(5 x+y=7\)
- B \(3 x+y=5\)
- C \(x+y=3\)
- D \(x-y+1=0\)
Answer & Solution
Correct Answer
(B) \(3 x+y=5\)
Step-by-step Solution
Detailed explanation
Let required equation of line is \(y=m x+c\) Since, angle between \(y=m x+c\) and \(y=2 x+1\) is \(\tan 45^{\circ}\)…
