Step-by-step explanation:

Given coordinates are(x

1

,y

1

)=(4,−1)

and (x

2

,y

2

)=(−2,−3)

Means of trisection:- A line segment in three equal parts then ratio is 1:2 and 2:1 internally.

Case (1) If m

1

:m

2

=1:2

Then, using formula

(x,y)=(

m

+m

(x,y)=(

Case (2):-

If m

=2:1

Then, using formula

(x,y)=(
