Question:
<p>In a <span class="math-tex">\(\triangle\)</span>ABC, if A (2 ,-1), B (-3, -2) and equation of angle bisector of <span class="math-tex">\(\angle B\)</span> of triangle is 3x - 2y + 5 = 0, then equation of BC is :</p>
<p style="display:inline">x + y + 5 = 0</p>
<p style="display:inline">x - 5y - 7 = 0</p>
<p style="display:inline">5x + y + 17 = 0</p>
<p style="display:inline">4x + 9y + 30 = 0</p>
Step-by-Step Solution
Key Concept: The reflection of a vertex (A) about the internal angle bisector of another angle (B) must lie on the line containing the opposite side (BC).
<p>5x + y + 17 = 0</p>
Correct Answer: C
