Question

find the co-ordinates of the point which divides the join of. ( -1,7 )and(4, - 3) in the ratio 2:3

Answer 1

hey mate ur answer is
⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇
=> let (x1,y2)=(-1,7)
=>(x2,y2)=(4,-3)
m1=2. m2=3
We know that,
X=m1x2+m2x1 /m1+m2
=>2×4+3×(-1) / 2+3
=>8-4 /5
=>x=4/5

y=m1y2+m2y1/m1+m2
=>2×(-3)+3×7/2+3
=>-6+21/5
=>15/5
=>3

So the coordinates of (x,y)=(4/5,3)

hope it help u
