Question

The ratio in which the x-axis divides the line segment joining the points A(3,6) and B(9, -3) is​

Answer 1

Answer:

k=1/2

Step-by-step explanation:

Given:

points A(3,6) and B(9,-3)

To find:

The ratio in which the x-axis divides the line segment

Solution:

let the ratio be k:1

the co-ordinates of the point dividing A and B into the ratio k:1 be (x,0)

by section formula,

0= -3k+6 /k+1

-3k +6 =0

-3k=-6

k=1/2
