⇒ অভ্যন্তরীণ বিভাজনের সূত্র= {[(mx2 + nx1)/(m + n)], [(my2 + ny1)/(m + n)]}

⇒ এখানে, x1, y1 = (- 1, 0) এবং x2, y2 = (2, 6). m : n = 2 : 1

⇒ [(2 × 2) + (1 × - 1)]/(2 + 1), [(2 × 6) + (1 × 0)]/(2 + 1) = (1, 4)

∴  বিন্দুদ্বয় (- 1, 0) এবং (2, 6)কে সংযোগকারী রেখাংশটি যে বিন্দুতে 2 : 1 অনুপাতে অভ্যন্তরীণভাবে বিভক্ত হচ্ছে সেই বিন্দুটি হল (1, 4)
