Question

find the value of K in which point p (2,k) divides the join of A (4,-9) and B (-3,5) in the ratio 5:2

Select one:
I)none of these
ii)-5
iii)1​

Answer 1

well the ratio should be 2:5

then and is -5

use formula that (X , y) divides (X1 ,y1) and (X2 ,y2) in ratio m is to n

then

x = (mx2 + nx1) /m+n

y =( my2 + ny1 )/m+n
