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(9-x)

x+1 = 36-4x

5x = 35

X = 7.

y-(-2) = 4(3-y)

y+2 = 12-4y

5y = 10

Y = 2.

P(7,2).
