Question

if A(-1,3), B(-3,7), C(1,-1) then A divides BC in the ratio

Answer 1

Answer: 1:1

Step-by-step explanation:

A<-1,3> divides BC

let us assume that the ratio is in the form k:1

(m1)(x2)+(m2)(x1)\m1+m2 ,( m1)(y2)+(m2)(y1)\m1+m2

=k-3\k+1 =-1 ,-k+7\k+1=3

=k-3=-k-1

=2k=2

k=1

therefore the ratios are 1:1

Answer 2

Step-by-step explanation:

A(-1,3)=(x,y)

B(-3,7)=(X1,y1)

C(1,-1)=(X2,y2)

x1-x:x-x2

-3+1:-1-1

-2:-2

1:1
