Question

Find the ratio in which the points (a,7) divides the line segment ab given a(-5,6) b(4,10).find the value of a

Answer 1

let the ratio be k:1
then by using section formula,
m1=k m2=1 point a be (x1,y1) & point b be (x2, y2)
7 =10×k+1(6) / k +1
7k+7 = 10k+6
7-6=10k-7k
1=3k
k=1/3
Hence ratio will be 1:3.
