Answer:
k = -8
Step-by-step explanation:
The line segment is divided into 3 equal parts 1:1:1.
:. P divides the line into 1:2.
A(2,1) x1= 2 y1= 1
B(5,-8) x2= 5 y2= -8
P(x,y) m1= 1 m2=2
USING SECTION FORMULA P(x,y) = m1x2+m2x1/m1+m2 , m1y2 + m2y1/m1+m2
= 1(5)+2(2)/3 , 1(-8)+2(1)/3
= 5+4/3, -8+2/3
= 3, -2
- x=3 and y= -2
2x-y+k=0
2(3)-(-2)+k=0
6+2+k=0
8+k=0
k= -8
