In what ratio does the point P(–4, 6) divide the line segment joining the points.
A(– 6, 10) and B(3, –8) ?

Given:

A = (– 6, 10)


B = (3, –8)


P = (–4, 6)


Let the ratio in which P (–4, 6) divides the line segment joining the points A (– 6, 10) and B (3, –8) be k: 1


We know that by Section formula,




This gives 2 equations,


1.



⇒ -4(k + 1) = 3k + (-6)


⇒ -4k – 4 = 3k – 6


⇒ 3k – 6 + 4k + 4 = 0


⇒ 7k – 2 = 0



2.



⇒ 6(k + 1) = -8k + 10


⇒ 6k + 6 = -8k + 10


⇒ 6k + 6 + 8k – 10= 0


⇒ 14k – 4 = 0



Hence, Ratio = 2: 7
