prove
please tell meeee​

Answer 1

Step-by-step explanation:

i am answering your line segment one question

k 1

_____________________

A P B

(3,7) (0,y) (-3,6)

let the point P (0,y) divided by y axis

let A(3,7) , B(-3,6) be the given point

let the ratio be k:1 (it will be easier to take k:1)

0=3x1+(-3)k

k+1

0=3-3k

3k=3

k=3/3

k=1

•°•ratio = 1:1

or

if we take ratio m:n

0=3m+(-3)n

m+n

0=3m-3n

-3m=-3n

m/n=-3/-3

m/n=1

•°•ratio = 1:1
