Find the ratio in which P(4, m) divides the line segment joining the points A(2, 3)
Coordinate Geometry (10)Find the ratio in which P(4, m) divides the line segment joining the points A(2, 3) and B(6, -3). Hence find m.
Answer
Let AP : PB = k : 1
$$ \frac{6k +2}{k + 1} = 4 $$
k = 1, ratio is 1 : 1
$$ m = \frac{-3 + 3}{2} = 0 $$
