Answer 2

Answer:

Step-by-step explanation:

If a point P = (x , y)P=(x,y) divides the line joining two points A = (a , b)A=(a,b) and B = (c , d)B=(c,d) in the ratio m : nm:n internally, then the coordinates of PP are given by

P (x,y)=(  m+nc⋅m+a⋅n ,  m+n d⋅m+b⋅n  ).

If PP divides ABAB externally in the ration m : nm:n, then

P (x,y)=( m−n c⋅m−a⋅n ,  m−n d⋅m−b⋅n  ).
