Find the ratio in which the line segment joining the points (– 3, 10) and (6, – 8) is divided by (– 1, 6)

Let the ratio in which the line segment joining (- 3, 10) and (6, - 8) is divided by point (- 1, 6) be k : 1

Therefore,


-1 =


-k – 1 = 6k – 3


7k = 2


k =


Therefore, the required ratio is 2: 7

To conduct Sports Day activities, in your rectangular shaped school ground ABCD, lines have been drawn with chalk powder at a distance of 1m each. 100 flower pots have been placed at a distance of 1m from each other along AD, as shown in Fig. 7.12. Niharika runs th thedistance AD on the 2nd line andposts a green flag. Preet runsththe distance AD on the eighth lineand posts a red flag. What is thedistance between both the flags? IfRashmi has to post a blue flag exactlyhalfway between the line segmentjoining the two flags, where shouldshe post her flag?
