Question

solve the given problem

Answer 1

Answer:

K2B this is a good answer

Answer 2

let the line be as follows:

.----------------.-----------------------.

P                 A                        Q

given ,  PA / PQ = 1/3

so,       PA / QA = 1/2

so, using section formula,

   $x=[\frac{2*2+5*1}{1+2} ]$

so x= 3

and $y = [\frac{2*1-8*1}{1+2} ]$

so y=-2

so, point A is (3,-2)

if the line 2x-y-k=0 pass throuh a so putting the coordinates of A,

                2*3-(-2)-k=0

                6+2-k=0

                 k=8

      If you like my way of drawing the line PQ
