In what ratio does the point (-4, 6) divide the line segment joining the points A (-6, 10) and B(3, -8)?
Given points are A (-6, 10) and B(3, -8)
Let the point C(-4, 6) divide AB in ratio m:n.
By section formula,
x = , y =
For point C(-4, 6) on the line joined by the points A and B.
-4 = …(1)
And, 6 = …(2)
Solving 1,
-4(m + n) = 3m - 6n
∴4m + 4n = -3m + 6n
∴ 7m = 2n
∴ =
Hence, ratio is 2:7.
