Question

29. If P(-9a-2, -b) divides the line segment joining A
(3a+1, -3) & B (80,5) in the who 3:1 find the values
of a & b.​

Answer 1

Answer:We have,

ABAP=31= AP+PBAP=31→ 3AP=AP+BP

→ 2AP=BP

BPAP=21

So, P divides AB in the ratio 1:2.

:Coordinates of Pure(1+21x5+2x2,1+21x-8+2x1)

=(3,2)

Since,P(3,2) lies on the line 2x-y+k=0.

.:2*3-2+k=0 → k=-4
