Find the co-ordinates of the points of trisections of the line segement joining the points (3-1)and (6,8)
Answers
Answer:
I can try....
Step-by-step explanation:
here if we trisect the line, we have
let A(3,-1) and B(6,8) and p and q are the points on the line segment AB which trisects it. understand?
now if line trisect then it has 3 equally parts.
so for P point we have ratio 1:2 and for Q point ratio is2:1.
because line has 3 equally parts.
now, using section formula, we have,,,
x=(m1)(x2)+(m2)(x1)/m1+m2
x=(1)(6)+(2)(3)/3
x=6+6/3
x=12/3=4
x=4.....
now,,
y=(m1)(y2)+(m2)(y1)/m1+m2/
y=(1)(8)+(2)(-1)/3
y=8-2/3,,, y=6/3=2....
y=2.........
these are coordinates for point P.
now for Q point we have, I write shortly? ok...
x=(2)(6)+(1)(3)/3
x=12+3/3,,,,, x=15/3=5,,....
x=5......
now for y, we have
y=(2)(8)+(1)(-1)/3
y=16-1/3,,,, y=15/3=5
y=5,,,,,
these are coordinates for point Q.
hence,
P=(4, 2)
Q=(5, 5)
I hope it's helpful for you,,,......
thank you.....
