Find the co-ordinates of the point P which divides the line-segment joining the points A (2, -6) & B (3, 5) in the ratio 2:1 externally.
Explanation:
Coordinates of a point dividing (x1, y1) and (x2, y2) in the ratio a : b externally is given by bx1-ax2a-b, by1-ay2a-b
∴ The coordinates of point P are 2×3-1×22-1, 2×5-1×-62-1 = (4, 16)
Hence, option (a).
