Q. 1 C4.8( 6 Votes )
Find the co-ordinates of the point which divides the line segment joining two point s in the given ratio for the following:
(–1, 2) and (4, –5); in the ratio 3: 2 externally
Answer :
Let the co-ordinates of the point which divides the line segment be (x, y) –
And, we know, By section formula
(where, m and n are the ratios, (x1, y1) and (x2, y2) are the coordinates of the line segment.)
⇒ x = 14
And,
⇒ y = – 19
∴ The co-ordinates of the point which divides the line segment joining two point s in the given ratio is (14, – 19).
