Question

Find the co-ordinates of the point which divides the line segment joining the points (3,4) and (7,9)internally in the ratio 2:3

Answer 1

the coordinates of the point are 23/5&6 respectively (using section formula)

Answer 2

HI

By using section formula,
        mx2 + nx1 , my2 + my1
        --------------   --------------
           m+n             m+n
X1,Y1 =3,4
X2,y2=7,9
m,n 2,3
     =2*7+3*3\2+3, 2*9+3*4\5
     =14+9\5,18+12\5
     =23\5,30\5
     =23\5,6

Therefore, the coordinates are 23\5,6
