The equal sides of an isosceles triangle are given by equations \(7 x-y+3=0\) and \(x+y-3=0\). If the slope \(m\) of the third side is an integer, then \(\mathrm{m}=\)
- A -3
- B 3
- C 4
- D -1
Answer & Solution
Correct Answer
(A) -3
Step-by-step Solution
Detailed explanation
Let \(\triangle \mathrm{ABC}\) be the isosceles triangle where \(\mathrm{AB}=\mathrm{AC}\) Hence Bisector of Angle \(\angle B A C\) will also be the perpendicular on line \(\mathrm{BC}\). Let \(m_1\) and \(m\) be the slopes of bisector lines AP and line \(B C\) respectively.…
