Question

in what ratio does y axis divides the line segment joining the points P - 4, 5 and 3, - 7 find the section.​

Answer 1

Answer:

if the point is on y axis it means x=0

let the ratio be k,:1

SECTION FORMULA:

(m1x2 + m2x1)/(m1 + m2 ) , (m1y2 + m2y1)/(m1 + m2 )

0,y=k(3)+1(-4)/k+1, k(-7)+1(5)/k+1

0=3k-4/k+1

3k-4=0

k=4/3

ratio is k:1=4/3 :1=4:3

now y=k(-7)+1(5)/k+1

  REPLACE WITH RATIO

4(-7)+3(5)/4+3=y

y=-28+15/7

y= -13/7
