1.	Find the co-ordinates of a point which divides the line joining the points `A(5, -2) and B(4, 6)` in the ratio 1 : 2 externally.
Answer» Let ` A(x_(1), y_(1))=(5, -2)and B(x_(2), y_(2))=(4, 6 )` `" "m:n =1:2` Let `P(x, y)` be the point which divides the line segment AB in the ratio `m : n ` externally. `therefore" "x=(1(4)-2(5))/(1-2)=6` `" "y=(1(6)-2(-2))/(1-2)=-10` `therefore` Co-ordinates of required point = (6, - 10)
