Question

If the point P (1, 1) divides the line segment joining the points A and B (-1, -1) in the ratio 5:2,

then the coordinates of A are​

Answer 1

Answer:

Thus Point B is(6,6)

Step-by-step explanation:

let the A is (x,y),B (-1,-1)

here m=5 and n=2

Then P is:

{ (5*-1 +2x)/7,  (5*-1+2y)/7}

Coordinates of P are (1,1)

so -5+2x/7=1

-5+2x=7

2x=12, x=6

also -5+2y/7=1

so -5+2y=7

2y=12,y=6

Thus Point B is(6,6)
