If \((4,3)\) and \((1,-2)\) are the end points of a diagonal of a square, then the equation of one of its sides is
- A \(4 x+y-11=0\)
- B \(2 x+y=0\)
- C \(2 x-3 y+1=0\)
- D \(x-4 y-9=0\)
Answer & Solution
Correct Answer
(D) \(x-4 y-9=0\)
Step-by-step Solution
Detailed explanation
Slope of \(A C=\frac{3+2}{4-1}=\frac{5}{3}\) \(\therefore \tan 45^{\circ}=\left|\frac{m-\frac{5}{3}}{1+\frac{5 m}{3}}\right| \Rightarrow 1=\left|\frac{3 m-5}{3+5 m}\right|\)…
