Q2 of 48 Page 102

Find the coordinates of the point which divides the line segment joining the points (5, –2) and externally in the ratio 7 : 9.

We know that


Coordinates of a point P(x,y) dividing the line segment joining A (x1, y1) and B (x2, y2) in the ratio m:n externally are


We have A → (5, –2)


and B → or B


Coordinates of point P (x,y) dividing AB in the ratio 7:9 externally are




is the required point.
