Question

Point P divides the line segment joining the points A(2,1) and B(5,-8) such that AP/AB = 1/3 . If P lies on the line 2x - y + k = 0, find the value of k answer is -4.g

Answer 1

By section formula-

x=1*5+3*2/4

=11/4

Y=1*-8+3*1/4

= -5/4

Putting the value in equastion-

2*11/4+5/4+k=0

K=-27/4

Hope this may help you.
