Find the coordinates of points of trisection of the line segment joining the points
A(-2, 8) and B(4,12)
(0,283)(2,323)
m1:m2=AP:PB=1:2
(x1,y1)=(−2,8)(x2,y2)=(4,12)
∴x=m1x2+m2x1m+n=1(4)+2(−2)3=0
∴y=m1y2+m2y1m+n=1(12)+2(8)3=283
P=(0,283)
m1:m2=2:1
∴x=m1x2+m2x1m+n=2(4)+1(−2)3=2
∴y=m1y2+m2y1m+n=2(12)+1(8)3=323
Q=(2,323)
