Question

find the ratio in which the point (2,1) divides the line segment joining (4, -5) , (-2, 7) ​

Answer 1

Step-by-step explanation:

x1=4, y1=-5, x2= -2 , y2= 7

X=2 Y=1

ratio = m:n

by Section formula

X = mx2+nx1 ; Y = my2+ny1

m+n. m+n

2 = m*-2 + n* 4. ; Y = m*7 + n*-5

m+n. m+n

2(m+n)= -2m+4n

2m+2n= -2m +4n

2m+2m=4n- 2n

2m = 2n

m = 2

n. 2

m:n = 1:1
