6. If the line segment joining the points A(4, -5) and B(4,5) is divided by the point P such that AP/AB = 2/3. Find the co-ordinate of P.

 \bold \orange{given} \:  \:  \bold \red{ \frac{ap}{ab}  =  \frac{2}{3}}

 \bold \purple{↦} \:  \bold \pink{ \frac{ab}{ap}  =  \frac{3}{2}}  \\  \\  \bold \purple{⟼} \:  \bold \pink{ \frac{ab}{ap}  - 1 =  \frac{3}{2} - 1} \\  \\  \bold \purple{ ⟼} \:  \bold \pink{ \frac{pb}{ap}  =  \frac{1}{2}} \\  \\  \bold \purple{ } \:  \bold \pink{coordinates \: of \: p}

 = ( \frac{mx2 + nx1}{m + x}  \:  \:  \frac{my2 + xy1}{m + x} ) \\  \\ =  ( \frac{2 \times 4 + 3 \times 4}{2 + 3}  \:  \:   \frac{2 \times 5 + 3 \times ( - 5)}{2 + 3}) \\  \\   = \frac{8 + 12}{5}  \:  \frac{10 -15 }{5}   \\  \\  = (4 \:  \:  \:  \:   - 1)

Coordinates of P = (4, -1)
