Question

find the co ordinates of the points which derides the line joining the points (1 , 3) & (2 ,7) in the ratios 3: - 4​

Answer 1

Answer:

(-2) , (-9)

Step-by-step explanation:

Given,

Points= (1,3) & (2,7) , ratio= 3:-4

m=3

n=-4

X=1

Y=3

X'=2

Y'=7

Therefore, By the mid-point theorem,

(x,y) = (mX'+nX/m+n) , (mY'+nY/m+n)

= (3×2+(-4×1)/3+(-4)) , (3×7+(-4×3)/3+(-4))

= (6-4/-1) , (21-12/-1)

= (2/-1) , (9/-1)

= (-2) , (-9)
