I don't understand this,so can you please explain more clearly. Where did you get the 1/5?
1.The point P divides the interval joining A(1,2) to B(9,3) internally in the ratio 4:1. Find the coordinates of P.

A(1,2),P(x,y),B(9,3).
x(1) = 4(9x)
x+1 = 364x
5x = 35
X = 7.
y(2) = 4(3y)
y+2 = 124y
5y = 10
Y = 2.
P(7,2).
