Question

if the points (-1/3,0) divide the line joined by(1,-2) and (-3,4) find the ratio​

Answer 1

Answer:

Step-by-step explanation:

(1,-2)............k..............(-1/3,0)..........1.................................(-3,4)

let the point (-1/3,0) divides the line segment in k:1 ratio

then

-1/3 = (-3×k + 1×1)/(k+1)

-1/3 = (-3k+1)/(k+1)

cross multiplying, we get,

-k-1 = -9k+3

8k=4

k=1/2

there fore point (-1/3,0) divides the line in 1:2 ratio
